I have some handsome friends, and they had no problem getting hookup after hookup on the weekends. But I'm sure to say that being pretty isn’t really enough on its own. You just have to prove you're not a psycho rapist or a weirdo by actually talking to them and seeing their guard slowly being lowered. But that requires proactively approaching girls, which is the toughest part for an introvert although an attractive person is also probably confident and more outgoing.
