I know a bunch of losers who are in there selling hot air about themselves etc. Many. And I have some friends who are in there all the time and shag like 4-5 girls a week. Women in there are mostly nuts, whores or married or all of that. "Mostly" meaning like 80-90%. Now if you're just looking for an easy fwck, do it. Don't forget protection at all times, because the girls you'll meet there have been around a lot. And watch out for husbands and jealous boyfriends.
But if you like yourself, stay away from all that and try getting into more new real-life social activities where you can meet real people, that's the best advice I can give you.
