my wife wanted to discuss numbers when we started dating and i told her that i never liked discussing that because the girls always lie about it. i wasn't trying to be funny or cocky or anything. it's just how i really felt about it. it kind of pissed her off and it kept coming up for a while but eventually it faded away after i continued to show no interest.
i never really felt that all guys lie. guys who aren't interested in playing the field don't lie and guys who play it well don't lie. it's the guys who want to play the field but suck at it that lie.
the key/lock analogy is actually a very good one -- if used to describe the general viewpoint of the masses. but it is a very shitty one to follow. women and men alike should be able to do whatever the fuck they want in their own private lives without being judged or shamed.
as a dad of a daughter and two sons, i feel differently about this. the way fathers feel about this stuff could be something that has contributed heavily to this over the years, as dads and moms probably put way more pressure on daughters than sons. but i do know that if one of my kids was slutting it up when they get older, i'd definitely prefer it be one of my sons. pretty sure my wife would feel the same way about it. i want my daughter to have a normal, healthy love life but definitely don't want her out bar slutting it up.
