LOL if you are a pretty boy you can continue to pull women forever, especially if you act fairly masculine. You can pull like crazy all through your 20's, probably into your 30's, for sure into your 40's, and even into your 50's. Hell, you can even pull in your 60's. Women will always love goodlooking men, and anyway extreme pretty boy features tend to lessen with age.
But your observation is correct. It's teenage girls who love pretty boys the most, and pretty boys can keep pulling teenage girls all through their 20's, 30's, 40's and even 50's if they have good enough Game. Hell they can even pull JB's far into your 50's if you want to risk it!
As women get a bit older, they are suspicious of pretty boys. They think they are all players or gay. But it doesn't matter. They still fuck them anyway. They will fuck them and then complain he's not masculine enough or keep asking him if he's bi, and they might try to cuck him due to perceived femininity, but they will keep fucking them like crazy 24-7 no matter what they think of them. Women will always love handsome men, and pretty boys are usually just considered "handsome" as they get older.
You don't have to look masculine or even act masculine to get women. It's all a bunch of crap. If you've got the looks, you can be a very soft, pretty, sensitive and even shy man and chicks will still practically rape you. They'll bitch that you're not manly enough but so what. This is where Looks Theory kills everything else. Looks Theory mogs Masculinity Theory hard.
One problem of pretty boys is people keep thinking they are gay or bi all through their lives. And they have to fend off faggots like fucking mosquitoes in Alaska. I knew a few guys who were male models, and they had so many faggots after them that they were getting homophobic. They kept saying they were going to deck the next fag who hit on them.
Basically everyone wants to fuck pretty boys. Faggots go crazy and drool over them. Teenage girls and even JB's are nuts about them even into late middle age, and women love them to death. If you are a pretty boy, it seems like the whole world wants to fuck you. Plus you can pull like crazy and get some big lay counts. This feeds the ego, builds confidence, and hones their Game. The most killer Game I have ever seen was on fairly masculine pretty boys - basically androgynes. These guys were simply incredible. One guy I knew would actually fuck three or four chicks a day. One in the morning, another in the afternoon, another in the evening, and he would climb in some JB's window at midnight.
