No... there are even younger girls for the young guys

I don't see much that makes young men any less mature than young women. It's expressed differently, sure.
That being said, I think men have a longer range of being sexually desirable. For girls, it's like they get a lot of attention all focused into a shorter range of ages, while for guys, it's more diluted, but spread out over a longer period.
Now yes, I think guys do face more sexual frustration for a longer period because out libido starts earlier, and girls don't seem to like us until we are older, as you say. But that doesn't necessarily translate to being bad in the sack. Many girls I know seem to like the overall kind of sexuality from guys who weren't chiseling bedposts. That they seem to be more romantic, in appreciating more of the non-intercourse aspects of sexuality. And I'm all for girls loving that stuff instead of chasing some BS "alpha" who can mimic the basest of animal urges while missing the intricacies of human sexuality and romance. If that means I have to wait longer, so be it.
