I don't disagree: there needs to be a great deal of education about consent long before college. I don't think it should be confined to formal lessons in a sex ed class. I think it needs to be much more all encompassing than that. Just as we now teach kids, more explicitly, about stranger danger and good touch/bad touch, we also need to teach kids about the emotional and the social aspects of sex and how those are affected by age, circumstance, context, and so on. It's not like a 3 week unit in a discreet class. BTW, in the US, sex ed is not universally taught at any age or with any universal curriculum. In some places, it's not really taught at all. And sometimes, incorrect information is given out.
The objective is to make drunken sex a taboo in the sense that a person's own moral code should prohibit them from having sex with drunk people, and when their personal judgment fails in that regard, there should be negative social consequences (within the peer group) for having sex with a drunk person. In other words, enlighten kids about the consequences of having sex with drunk people, and when that fails, shame the shit out of them.
But a boy who has many sex partners is celebrated; a girl who has many sex partners---and in high school and college, many can be more than one-- is called bad names and is much more vulnerable to future sexual assaults.
Boys/men are threatened by girls/women who have had many sex partners, and multiple misconceptions have been built up around it. An education program would need to shine a light on the causes of this phobia as well as the misconceptions. Take away the reasons for boys to shame girls for having sex.
Men's aversion to promiscuous women may be rooted in a primal fear of being cuckolded, a fear that isn't relevant any more, even if one considers paternity fraud. Boys don't have any particular reason to care that girls are having sex, petty jealousy notwithstanding.
The myth that promiscuous women collect men's fluid or become loose and numb should also be debunked. The myth that virgins are tighter needs to be clarified to point out that virgins are only tighter because they are nervous; it is a sign of lack of arousal and therefore undesirable.
And if boys are no longer threatened by promiscuous women, then girls no longer have a weapon they can use against their rivals.
