I have an idea. Make them go to sex ed. The parents can tell them "The homosexuals and people who use condoms and have sex before marriage that you're hearing about are all going to hell." I don't see how learning that contraceptives exist and that penises go in vaginas and that some penises go in male anuses will hamper their parents ability to teach them their religious beliefs.On another note, at my private catholic school, we had sex ed, in which at one point I think the teacher concluded with "If you ever have sex before marriage, use a condom. But sex before marriage is wrong, and you shouldn't have sex before marriage. So you'll never need to use a condom because you'll never have sex before marriage. But if you do, use a condom."
