Sure, sure, that’s one way to do it. Or you could not get married but still be faithful. Or you could wear a condom (even if you are faithful and/or married). Or you could masturbate. Masturbating is always safe, unless you do it when you’re supposed to be landing an airplane or driving a racecar or testifying in court.
You know, I’m so tired of this idea that safe sex can only occur within the bounds of a marriage (and presumably a heterosexual monogamous Christian marriage at that). This mindset leads to the dreadfully stupid “abstinence only” sex “education”. In abstinence only sex “education”, students are told to fight their primal urges to bump uglies until they are safely within the realm of matrimony. Very little discussion (if any at all) is given to topics like safe sex and birth control.
Can you imagine if Drivers Ed took a similar approach? They might tell students that the only way to prevent car accidents is not to drive at all. That’s technically correct, but children are going to drive, and they need to know about seatbelts and airbags.
The fact is that abstinence only sex “education” does not work. While teaching students about condoms may not alter their behaviors regarding contraception, not teaching them about condoms doesn’t keep them any safer.
Yes, it is true that the only 100% surefire way to avoid getting pregnant or contracting a sexually-transmitted infection is to abstain from having sex. It’s also true that sex is really fun and a lot of people really want to do it. It’s irresponsible to pretend that telling kids to wait until marriage will actually cause them to do so. It would be a better idea to stop pretending that teenagers are pious and chaste, and start teaching them how to make good decisions.
