I don't agree there is a youth culture. There's only a youth culture among young kids. Which only is a problem for an older person if they themselves would prefer to fuck young kids. So then they're so to speak, part of their own problem.
All older guys I know who fuck young girls have all truck loads of issues. I'm not sure they're the right men to educate our youth. There's a maturity issue.
And just to make it clear, I'm not talking about being a sexual mentor for somebody young. Which is a great thing, and something more should do....but that doesn't necesarily involve having sex with them.
I've always liked women on my own level of maturity, (which ever age it may be) which means that they're most likely to be my own age.
