Hmm I haven't heard of this before. Sounds like an interesting theory and I agree that they should promote it. I thought you'd say something along the lines of the parents are against it. This seems to happen a lot, parents neglect what they did in their lives and believe that they can protect their kids against it... Personally I don't understand it at all, it is human nature to have sex, it is what caused us to be here now!
Just further adds to my thought that the human race will not be wiped out by mass explosions, volcanoes or anything bigger than us. The only things that we cannot control are the things too small to see.
