I have a friend who, devastated that at 23 he had never so much as kissed a girl, tried to hang himself. I survived adolescence with my virginity intact for one basic reason. My father discussed these issues with me and did what he could to impart his moral fiber to me. While that makes me unusual and a possible outcast with my peers, I don't care. It is who I am.
Many teens have neither the family nor the church.
They desperately need not just information, but also access to quality, affordable, completely confidential reproductive health care. Teens have sex to have sex, not to reproduce. Let's give them the same tools that adults have to keep the two separate. I learned very little about sexuality from school, home, or church. I had to go and seek information in the various media.
