yes, they are very different.
examples:
1. walk up to a black woman and speak, and you either get the hand, a "nigga please" look or a "whatever" look... unless she finds you attractive. nothing wrong with that... just how it is. walk-up to a white gal and speak, and she's scared about 10% of the time, but 90% of the time, they start talking and can't shut-up.
2. 3 fully-clothed white gals + 1 bottle of absolut VERSUS 10 naked black women in a pool: in which situation will the fucking happen faster, quicker, easier, and all damn night?
3. hey baby, can I borrow $30? black woman: "betta ask ya maw for it... ole broke ass nigga." white woman: "sure baby... here's $100... my Dad won't miss it."
4. black woman: giiiiirl, dem blue jeans is coochie cutters... pull that down. white woman: becky, is my pussy showing enough in these shorts or should i take my panties off to show it off more?
generalizations + stereotypes + bullshit = relax, i'm just having fun.
