Abstaining from sex is a good way not to get a sexually transmitted infection.
To get through life without any such infections, there are two choices: never have sex – ever, or never have sex except with a partner who has never had sex with anyone else, and never will.
As parents, it’s hard for us to think about our children growing up and becoming intimate with anyone, but, giving them narrow choices such as are described above is risky. Most of our teens and young adults want to heed our wishes and even, occasionally, our rules, but there are few perfectly obedient people in this world.
Rather than risking our children’s lives by assuming they will only do as we say, the safer choice seems to be arming our children with as much knowledge about disease prevention as possible, while continuing to share our values and beliefs.
To protect them, we tell them what we want, what we expect, and why, but we include the information they need to stay as safe as possible, should they make risky choices. Better they know how to have safe sex but not need the information, than need the info and not have it.
