To a collection of women in their first women in university.
I think the education comes in 2 parts.
1 I think educating men is the first and foremost in importance. Especially taking on hard wired attitudes in some cultures about honour and decency. It's time to fess up that some people in some religions look at women outside of their group as legitimate targets.
2 I think challenging and if need be censoring a lot of the sexual imagery out there. For example porn on the internet and rap music.
There's no point in having the best sex education in the world if some educationally subnormal with his underpants sticking out. Sings about bitches and hoes to impressionable youth. Too many kids first education in sex is watching hardcore 9and increasingly violent porn)
