The way girls share really personal things about guys in relation to sex.
Society and the media would have you believe that guys talk about sex all the time and just objectify the women that they’ve slept with. I don’t know if maybe I’m just hanging out with the wrong people, but honestly the most you usually get out of a guy is just that they had sex with a girl. And the only time we discuss details are when you’re just like trading stories.
But girls tend to like immediately report on things to their friends, and share details that honestly could be embarrassing or uncomfortable for the guy. It makes me really uncomfortable and creeped out to think that if I sleep with a girl I have to just accept that all of her friends are going to know every detail about the experience. Size, performance, how long it lasted, how I look. It just feels like a huge breach of privacy.
Make no mistake, it's intended only to give them the upper hand while doing absolutely nothing to earn respect. Call 'em on it, and don't let them damage your self-respect. There are worthwhile girls out there, probably conservative, and they're the only ones worth giving yourself to.
