Modern teen sexuality

How do atheists deal with sexual morality - Beliefnet
Abstinence education has been a total failure even among the most fervent believers not only because of peer pressure and cultural conformity, which are powerful drivers for sex. But in prehistory and until recently marriage was defined as having sex, and for women it normally happened shortly after puberty, for men a little later, probably because they had to compete with all of the successful men in the community for the available young women. But when you add breeding instinct to peer and social pressure, the only moral response is to teach responsible, contraceptive and prophylactic sex however you want to define responsible sex. Forget abstinence it is not responsible sex it is unnatural, anti-social, and anti-peer.

Responsible sex by my definition is informed consent by both partners, radical respect for the health, emotional needs and wishes of any sexual partner, (if you have sowed any wild oats, that means prophylactic sex until medically proven to be STD free six months after last oating) and an intent to form a pair bond leading to marriage and children at an appropriate time. It does not mean waiting for the appropriate time to have sex, it means contraceptive sex until then.
