I was watching over my sister's shoulder, and in the sitcom she was watching, a group of female friends were discussing how one of their husbands didn't perform in bed. It further reminded me of a post I'd seen a while back about how women in general seem to be totally fine discussing their sex lives with the gals, but dudes never really do this.
As far as my experience goes, that seems to be mostly correct. My girlfriend's let slip before that she's discussed what we've done in the bedroom with her circle of girl friends, something she didn't seem to see as a big deal. It's not particularly a big deal for me either, as I barely know her friends, but it's not something I expected. I have never once discussed my sex life with my friends, guy or girl. I mean yeah, lots of joking and discussion about porn and masturbation, but never when another person was involved.
So it has me thinking, why is this so? Seems like a reversal of the stereotype: women are more restrained about sex, while men never stop thinking about it. I'm not against talking about sex, but getting into specifics about an individual without their consent seems wrong.
