There is absolutely ZERO excuse for a parent who allows their 14-year-old to be have sex. They can't drive, they shouldn't be allowed to go anywhere unsupervised, they shouldn't be allowed to date except under very controlled circumstances, they can't rent a motel room, they don't have their own apartments.
You know where most 14yo kids who are having sex, have sex? I've read the studies, because I have a teenage child of my own and will have 3 more before I'm done. The place most 14yo kids have sex is in their own homes, between the time they're out of school and the time their parents come home from work. Given that the answer to preventing a sexually active 14yo is to arrange babysitting or have one parent quit work, which do you think shows more love for a child ... doing that, or putting them on a contraceptive???
I agree but it isn't always something "we" allow. It happens and usually without parents ever knowing.
