And then what happens when he gets to university and STILL has never approached a girl? Seriously, those crushes in high school serve a purpose, and it's good to act on them, learn to be social, learn how dating works (or more often, how it doesn't work). Like everything else good in life, it takes practice and experience before one is good at it.At that age, women are a distraction. Focus on yourself. Improve yourself, get into the university and learn something about the world around you. You don't have to chase the local fish, or even chase them. Be the big fish, and have them chase you.
Of COURSE at that age the opposite sex is a distraction (same thing applies to the girls who are distracted by all the cute boys). The thing is, you're only going to get over that distraction by acting on it. Either dating or getting dumped...either way, it brings the issue to resolution so you're not sitting around pining away. And, when you get crushed in high school, you bounce back, because it was never all that serious in the first place. It helps prepare you to still be able to recover when you're an adult and the stakes get a bit higher in relationships and resulting break-ups.
And, I happen to agree with Georgina that your assumption that the girl is going to head off to university and become promiscuous based on knowing absolutely nothing about her IS misogynistic.
