I'm also 37 years old.
Personally, I think men my age pursuing girls in that age bracket 18-21 is creepy and immature. 18? Macking on girls 2 decades younger than you? Come on dude.
There's going to be the typical dipsh!t PUA/red pill outrage that college girls are fair game to middle-aged men and that "age is just a number" and that "alpha males go for what they want" blah blah blah. Men in their late 30's should not be pursuing college girls. It's not age-appropriate behavior, and there's an epidemic these days of men refusing to grow the fvck up and act like men. It's called Peter Pan Syndrome. Grown-ass men in their 30's dressing up for Halloween and going out partying with kids a decade younger. It's a problem.
If one falls in your lap, fine (highly, highly unlikely to happen). But if you're pushing 40 and you're out at college bars and parties trying to run game at teen girls, that's pathetic. And people will think you're creepy. Including the girls you're hitting on.
There's an old adage -- half your age plus 7. So at 37, your dating pool is 25 and up. For me, I don't relate to women under 30 and in the few instances where I've taken a 20-something home after 35, I had little interest in
texting her again. Women in their early-mid 30's are beautiful to me. Maybe their physical appearance doesn't have the raw sexiness that women in the bloom of youth have, but neither does yours.
