Dr. Ray Bohlin provides a look at the many problems surrounding the idea of safe sex from a Christian, biblical worldview perspective as well as a scientific perspective. He provides a sound argument for supporting the Christian view of sex being reserved for the marriage relationship.

At age 16 John had sex with Andrea. Just one time. He enjoyed the experience but felt guilty and decided the risk of sexually transmitted diseases (STDs) and pregnancy were just too great. He did not have sex again until nine years later when he married Cindy, who was a virgin. Three months after their wedding Cindy began having painful symptoms. Unknowingly John, who had never had any symptoms of disease, had brought two STDs into his marriage. But John and Cindy were lucky; they both responded to treatment and are healthy today. Many others, however, are not so fortunate. Today STDs are at unprecedented and epidemic proportions. Thirty years of the sexual revolution is paying an ugly dividend, and those most at risk are teenagers. This is true partially because teenagers are more sexually active than ever before, but also because teenage girls are more susceptible to STDs than males or adult females.

While a few STDs can be transmitted apart from sex acts, all are transmissible by the exchange of bodily fluids during intimate sexual contact. I want to discuss the severity of the problem as well as what must be done if we are to save a majority of the next generation from the shame, infertility, and sometimes death, that may result from STDs.

If you are not aware of some of the following statistics, then prepare to fasten your seat belt because what I have to report is not pretty. The information I am about to share is from data gathered by the Medical Institute for Sexual Health in Austin, Texas.(1) All of these statistics are readily available from reputable medical and scientific journals.

Today, there are approximately 25 STDs. A few can be fatal. Some are relatively harmless, but all are humiliating. Many women are living in fear of what their future may hold as a result of STD infection. It is estimated that 1 in 5 Americans between the ages of 15 and 55 are currently infected with one or more viral STDs, and 12 million Americans are newly infected each year. That’s nearly 5% of the entire population of the U.S.! Of these new infections, 63% involve people less than 25 years old.

This epidemic is a recent phenomenon. Some young people have parents who may have had multiple sexual part-ners with relative impunity and conclude that they too are safe from disease. However, most of these diseases were not around 20 to 30 years ago. Prior to 1960, there were only two prevalent sexually transmitted diseases: syphilis and gonorrhea. Both were easily treatable with antibiotics.

In the sixties and seventies this relatively stable situation began to change. For example, in 1976, chlamydia first appeared in increasing numbers in the U.S. Chlamydia, particularly dangerous to women, is now the most common bacterial STD in the country. In 1981, human immuno-deficiency virus (HIV), the virus which causes AIDS, was identified. By early 1993, between 1 and 2 million Americans were infected with HIV or AIDS, over 12 million were infected worldwide, and over 160,000 had died in the U.S. alone. Then herpes was added to the mix. This STD now infects 30 million people.

In 1985, human papilloma virus (HPV) began a dramatic increase. This virus can result in venereal warts and will often lead to deadly cancers.

By 1990, penicillin-resistant strains of gonorrhea were present in all fifty states, and by 1992 syphilis was at a 40-year high. As of 1993, pelvic inflammatory disease (PID), which is almost always caused by gonorrhea or chlamydia, was affecting 1 million new women each year. This includes 16,000 to 20,000 teenagers. This infection can result in pelvic pain and infertility and is the leading cause of hospitalization for women between the ages of 15 and 55, apart from pregnancy.

Pelvic inflammatory disease can result in scarred fallopian tubes which block passage of a fertilized egg. The fertilized egg, therefore, cannot pass on to the uterus, and the growing embryo will cause the tube to rupture. From 1960 to 1990 there was a 400% increase in tubal pregnancies, most of which were caused by STDs. Making matters even worse is the fact that 80% of those infected with an STD don’t know it and will unwittingly infect their next sexual partner.

The Medical Facts of STDs

Syphilis is a terrible infection. In its first stage, the infected individual may be lulled into thinking there is little wrong since the small sore will disappear in 2 to 8 weeks. The second and third stages are progressively worse and can eventually lead to brain, heart, and blood vessel damage if not diagnosed and treated. The saddest part is that syphilis is 100% curable with penicillin, yet there is now more syphilis than in the late 1940s, and it is spreading rapidly.

Chlamydia, a disease which only became common in the mid-1980s, infects 20 to 40% of some sexually active groups including teenagers. In men, chlamydia can cause infertile sperm, a condition reversible with antibiotics. In women, however, the infection is devastating. An acute chlamydia infection in women will result in pain, fever, and damage to female organs. A silent infection can damage a woman’s fallopian tubes without her ever knowing it. A single episode of chlamydia PID can result in a 25% chance of infertility. With a second infection, the chance of infertility rises to 50%. This is double the risk of gonorrhea.

Treatment with antibiotics is not always successful. One study reported that 18% showed a recurrence of infection within 3 weeks. As many as 14% of teenagers do not respond to treatment, and ultimately require a hysterectomy. It is an overwhelming burden for an 18- or 19-year- old girl to have to face the fact that she will never be able to bear a single child.

The human papilloma virus (HPV) is an extremely common STD. One study reported that at the University of California, Berkeley, 46% of the sexually active coeds were infected with HPV. Another study reported that 38% of the sexually active females between the ages of 13 and 21 were infected.

HPV is the major cause of venereal warts which are extremely difficult to treat and may require expensive procedures such as laser surgery. HPV can result in pre-cancer or cancer of the genitalia. By causing cancer of the cervix, this virus is presently killing more women in this country than AIDS, or over 4,600 women in 1991. HPV can also result in painful intercourse for years after infection even though other visible signs of disease have disappeared.

And of course there is the human immunodeficiency virus, or HIV, the virus that causes AIDS. The first few cases of AIDS were only discovered in 1981; now, in the U.S. alone, there are between 1 and 2 million infected with this disease. As far as we know, all of these people will die in the next ten to fifteen years. As of early 1993, approximately 160,000 had already died.

In 1991 a non-random study at the University of Texas at Austin showed that 1 in 100 students who had blood drawn for any reason at the university health center was HIV infected.

While the progress of the disease is slow for many people, all who have it will be infected for the rest of their lives. There is no cure, and many research-ers are beginning to despair of ever coming up with a cure or even a vaccine (as was eventually done with polio). In 1992, 1 in 75 men was infected with HIV and 1 in 700 women. But the number of women with AIDS is growing. In the early years of the epidemic less than 2% of the AIDS cases were women. Now the percentage is 12%.

Teenagers Face Greater Risks from STDs

One of the statistics I have mentioned is that teenagers are particularly susceptible to STDs. This fact is alarming since more teens are sexually active today than ever before. An entire generation is at risk, and the saddest part about it is that most of them are unaware of the dangers they face. Teenagers must be given the correct information to help them realize that saving themselves sexually until marriage is the only sure way to stay healthy.

The medical reasons for teens’ high susceptibility to STDs relates specifically to females. The cervix of a teen-age girl has a lining (ectropion) which produces mucus that is a great growth medium for viruses and bacteria. As a girl reaches her 20s or has a baby, this lining is replaced with a tougher, more resistant lining. Also during the first two years of menstruation, 50% of the periods occur without ovulation. This will produce a more liquid mucus which also grows bacteria and viruses very well. A 15-year-old girl has a 1-in-8 chance of developing pelvic inflammatory disease simply by having sex, whereas a 24-year-old woman has only a 1- in-80 chance in the same situation.

Teenagers do not always respond to antibiotic treatment for pelvic inflammatory disease, and occasionally such teenage girls require a hysterectomy. Infertility is an increasing problem in our society. It is estimated that one-fourth to one-third of all female infertility in marriage is a result of STDs.

Teenagers are also more susceptible to human papilloma virus, HPV. Rates of HPV infection in teenagers can be as high as 40%, whereas in the adult population, the rate is less than 15%. Teenagers are also more likely to develop precancerous growths as a result of HPV infection than adults. These precancerous growths in teenagers are also more likely to develop into invasive cancer than in adults.

Apart from the increased risk from STDs in teens, teen-age pregnancy is also at unprecedented levels. In 1985 there were over 1 million teen-age pregnancies; 400,000 of these ended in abortion. Abortion is not a healthy procedure for anyone to undergo, but this is especially true for a teenager. Not getting pregnant to begin with is far better. Oral contraceptives are not as effective with teenagers, mainly because teens are more apt to forget to take the pill. Over a one-year period, as many as 9 to 18% of teenage girls using oral contraceptives become pregnant.

Finally, when teenagers start having sex earlier in life, they are much more likely to have multiple sexual partners, a behavior that puts them at greater risk for STD. When teenagers become sexually active before they are 18 years of age, 75% of them will have more than 2 partners and 45% of them will have 4 or more partners. If sexual activity begins after the 19th birthday, only 20% will have 2 or more partners and only 1% will have 4 or more partners. (These statistics were reported by the Centers for Disease Control after interviewing people in their 20s.)

Is Safe Sex Really the Answer?

I must now take a hard look at the message of safe sex which is being taught to teens at school and through the media.

Some people believe that if teens can be taught how to use contraception and condoms effectively, rates of pregnancy and STD infection will be reduced dramatically. But common sense and statistics tell us otherwise. At Rutgers University, the rates of infection of students with STD varied little with the form of contraception used. For example, 35 to 44% of the sexually active students were infected with one or more STDs whether they used no contraceptive, oral contraceptive, the diaphragm, or condoms. It is significant to note that condoms, the hero of the safe sex message, provided virtually no protection from STDs.

Will condoms prevent HIV infection, the virus that causes AIDS? While it is better than nothing, the bottom line is that condoms cannot be trusted. A study from Florida looked at couples in which one partner was HIV positive and the other was negative. They used condoms as protection during intercourse. After 18 months, 17% of the previously uninfected partners were HIV positive. That is a one-in-six chance, the same as in Russian roulette.

Condoms do not even provide 100% protection for the purpose for which they were designed: prevention of pregnancy. One study from the School of Medicine Family Planning Clinic at the University of Pennsylvania reported that 25% of patients using condoms as birth control conceived over a one-year period. Other studies indicate that the rate of accidental pregnancy from condom-protected intercourse is around 15% with married couples and 36% for unmarried couples.

Condoms are inherently untrustworthy. The FDA allows as many as one in 250 to be defective. Condoms are often stored and shipped at unsafe temperatures which weakens the integrity of the latex rubber causing breaks and ruptures. Condoms will break 8% of the time and slip off 7% of the time. There are just so many pitfalls in condom use that you just can’t expect immature teenagers to use them properly. And even if they do, they are still at risk.

Studies are beginning to show that school-based sex education that includes condom use as the central message, does not work. A study in a major pediatric journal concluded that the available evidence indicates that there is little or no effect from school-based sex- education on sexual activity, contraception, or teenage pregnancy.(2) This study evaluated programs that emphasized condoms. In addition, programs that emphasize condoms tend to give a false sense of security to sexually active students and make those students who are not having sex feel abnormal.

The list of damages from unmarried adolescent sexual activity is long indeed. Apart from the threat to physical health and fertility, there is damage to family relationships, self-confidence and emotional health, spiritual health, and future economic opportunities due to unplanned pregnancy. Condom-based sex- education does not work.

Saving Sex for Marriage is the Common Sense Solution.

The epidemic of sexually transmitted diseases is running rampant in this country and around the world. Diseases such as chlamydia, human papilloma virus, herpes, hepatitis B, trichomonas, pelvic inflammatory disease, and AIDS have joined syphilis and gonorrhea in just the last 30 years. There is no question that the fruits of the sexual revolution have been devastating. I have also shown how our teen-agers are at a greater risk for sexually transmitted diseases than are adults and that sex-education based on condom use is ineffective and misleading. There is only one message that offers health, hope, and joy to today’s teenagers. We need to teach single people to save intercourse for marriage.

Sex is a wonderful gift, but if uncontrolled, it has a great capacity for evil as well as good. Our bodies were not made to have multiple sex partners. Almost all risk of STD and out-of-wedlock pregnancy can be avoided by saving intercourse for marriage. And it can be done.

Statistics show clearly that in schools that teach a sex education program that emphasizes saving intercourse for marriage, the teen pregnancy rate drops dramatically in as little as one year. In San Marcos, California, a high school used a federally funded program (“Teen Aid”) which emphasizes saving intercourse until marriage. Before using the program there were 147 pregnancies out of 600 girls. Within two years, the number of pregnancies plummeted to 20 out of 600 girls.(3) As of 1992, San Marcos was still using this program and was still satisfied with it. In Jessup Georgia, upon instituting the “Sex Respect” program, the number of pregnancies out of 340 female students dropped from 17 to 13 to 11 to 3 in successive years.

Delaying intercourse until teens are older is not a naive proposal. Over 50% of the females and 40% of the males between 15 and 19 have not had intercourse. They are living proof that teens can control their sexual desires. Of those who had at least one sexual experience, 20% had sex in the past but were not currently sexually active. Therefore, a minority of students are sexually active.

Condom-based sex-education programs basically teach teen-agers that they cannot control their sexual desires, and that they must use condoms to protect themselves. It is not a big leap from people being unable to control their sexual desires to being unable to control their hate, greed, anger, and prejudice. This is not the right message for our teenagers!

Teenagers are willing to discipline themselves for things they want and desire and are convinced are beneficial. Girls get up early for drill team practice. Boys train in the off-season with weights to get stronger for athletic competition. Our teens can be disciplined in their sexual lives if they have the right information to make logical choices.

Saving sex for marriage is the common sense solution. In fact, it is the only solution. We don’t hesitate to tell our kids not to use drugs or marijuana, and most do not. We tell our kids it’s unhealthy to smoke, and most do not.

It is normal and healthy not to have sex until marriage. STDs are so common that it is not an exaggeration to say that most people who regularly have sex outside of marriage will contract a sexually transmitted disease. Our sexuality should blossom within the confines of a mutually faithful monogamous relationship. We need to reeducate our kids not just in what is healthy, but in what is right.

    There is much talk about sexual activity I realise, but the sexual desire is strong – the bible therefore is our authority on such matters. I am single and 78, have sinned sexually at times and believe I am forgiven and that such sins are mostly past and wrong desire. There is, presumably, absolutely no justification for any sex outside marriage. End of story – any inclination we must resist and deny ourselves. Currently I am tempted, even at my age, to have some involvement. Even christians – yes, like me – fail to resist temptation sometimes. Masturbation is wrong – all one’s life at whatever age. Even being in bed with a female all night, just to ‘play around’, without any penetration, is a sin. So, I must conclude, that any sex at all is sinful, at any age of any sort.
    I assume my thoughtd, let alone desires or very occasional activity, is wrong. The Lord forgives, but it is always, I assume, however impossible, to have even the slightest activity – as I am currently tempted to do, with a single lady 10 years older than me – no use my deciding to be active for one minute then….. the Lord will not approve to any degree if I do, even if my christian friend agrees to some activity…… So, as I have always been single, NO SEX of any sort. So denying all activity is the rule and not to be broken?
    Well, for most of my life, I have not had sexual activity – some masturbation (which I thought ‘normal’ even as a young teenager). God will in His mercy forgive me, as He has, but NO MORE? None at any time? Any comments then please?

    Ray and I talked about your comment and question and decided to have me answer you. (I apologize for the wait.)

    I think perhaps focusing on “NO SEX” as an unfair deprivation is not helpful for one’s spiritual health. Psalm 84:11 says, “For the Lord God is a sun and shield;
    The Lord bestows favor and honor.
    No good thing does he withhold
    from those who walk uprightly.”

    If God appears to be withholding sex from unmarried people, then unmarried sex is not a good thing. (In fact, there are 44 biblical references to the sin of porneia, which refers to any kind of sexual behavior outside of marriage. It seems to be important to God!)

    I think that our culture’s obsession with sex as a right and a necessity (when it is neither) creates this kind of question–and makes it easy to believe the enemy’s lies that God is ripping us off when He says we are to say no to certain things.

    The same God who created our bodies took on human flesh–the same kind of body we have–when He left heaven to become man. Jesus lived His entire life without engaging in any sexual behavior (or even sexual thoughts other than being tempted by the enemy about them, Hebrews 4:15), so we know it’s possible.

    I think a better question than “No more sex, like EVER?” would be, “Given my singleness, how can I best glorify God in my body and in my sexuality?” 2 Timothy 2:21 talks about being “a vessel of honor,” set apart as holy and useful to the master of the house. When we live in light of eternity, concerned with glorifying God in every aspect of our lives, since that is what is ultimately important, then it makes sense that we should steward our bodies in purity and holiness.

    I also think it’s helpful to look at his question, like so many others, from an eternal perspective. 100 years from today, from the vantage point of heaven, do you want to be able to praise God that He helped you live a life of sexual purity and self-control in these days of temptation, or do you want to look back on your time on earth with regret that you didn’t follow Jesus’ example of saying no to the temptations of your flesh?

    The bottom line answer to your question is, I suggest, to ask yourself, “What will earn me the reward of hearing the accolade, ‘Well done, good and faithful servant?” when it comes to my sexual choices? How can I avoid losing that reward because my desire for fleeting sexual pleasure was greater than my desire to honor my Lord and my own body, as well any ladies I defraud by sinning against them as well?”

    I hope you find this helpful.

    Thanks a lot!
    Dr. Ray Bohlin sheds light on the complexities of safe sex from both a Christian and scientific perspective. He emphasizes the importance of reserving sex for marriage, sharing a cautionary tale of STDs affecting a married couple. STDs, which have reached epidemic levels, disproportionately endanger teenagers. Bohlin presents alarming statistics, highlighting the urgency of saving the next generation from the physical and emotional toll of STDs. He questions the effectiveness of safe sex education and advocates for abstinence until marriage as the only foolproof way to protect physical and emotional health. Ultimately, Bohlin asserts that saving sex for marriage is the sensible and healthy choice. 🙏📚 #SexualHealth #Abstinence #ChristianViewpoint #SafeSex #STDs
