I won't be teaching my kids abstinence, I think it's a recipe for disaster. I will teach them to respect themselves and to wait for the right time or person, how to cope with pressure to have sex and of course safe sex.
My thoughts precicely - DP on the other hand may disagree as he is sure his girls will not be dating until they are 30 - seriously though he also agrees that if they have a healthy self-esteem and the right support they will end up having sex for the right reasons and in a safe way.

ETA - I would be a hypocrite if I taught them anything else as I was 15 and had sex with my boyfriend who I did love (in a 15yo intense way) and I have no regrets.
