IMO to each his own, if you wanna wait more power to you, but it's not a MUST for me. People are ultimately going to do what they want to do, and the way society is set up right now, sex is everywhere. I don't want to sit there and tell my child he/she has to wait, cuz what if he/she goes out and does it anyway. So my approach is to tell him/her how important it is to wear protection, or to protect herself with BCP. At the same time, I don't believe in having sex with someone your not in a relationship with whatsoever.
