They were just talking about how they'd sometimes fuck a guy before they would suck his dick, and that's weird to me because all the white women I've ever known would totally suck a dick and not really think anything of it but GOING ALL THE WAY is like a big thing. Sistas? Who knew?
There's definitely a cultural thing there. I had a black female coworker who was hooking up with a manager at Blockbuster. When I asked her if she could get me some free rentals in exchange for *hand-on-back-of-head bobbing-up-and-down motion* she said "Oh, he's not getting THAT from me."
Maybe it's a result of white girls tending to care more about technical virginity? Even way after virginity's an issue, if they trained themselves to think of HJ's and BJ's as Not Sex, then it's natural that they'd be more casual with those.
The extreme version of this was a smattering of Catholic girls who allegedly would do anal with their boyfriends, but not vaginal. Virgin up front, martyr in the back.
