This doesn't have anything to do with mentality. The reason a male should genetically be attracted to a female is how fertile he perceives her as and late teenager is arguably the best age to reproduce. I'm not saying they should have children quite the opposite but it's not crazy to be aroused by how they look.
Any younger than that is not fertile at all, the reason a male would be attracted to a kid(say, 14yo and below) is because he's fucked up in the head very badly
