first of all, generalizing is ridiculous. each circumstance is different. just putting an arbitrary number on things doesn't make sense..
second of all, in these changing times of fukkery and ratchetness, 4 by that age is a godsend and borderline born again virgin status...gotta just deal with it.
sure most of the girls you meet at the bars/clubs are gonna be hoes...if you want the "good and clean" ones, you gotta meet them through mutual friends or very conservative settings. and if you find one of these "good" girls at a bar/club, they are probably seriously fukked up mentally and there is a reason they have slept with 4 or less, outside of religious beliefs or otherwise rare, strong principles.
plus at the end of the day, how you gonna know if theyre not lyin anyway? just find an honest one that treats you right and put numbers aside
