Are women ok with a guy brushing up against their butts...or just simply laying a hand on it without actually grabbing it?

I love it i feel seeexxxyyyy

No...unless i'm in a really sh*tty mood

It depends on whether or not it is a man I know or not. If a stranger brushes up against my bum by accident then I'd certainly forgive them for it. If they did it on purpose than I'd probably make a slightly disappointed face at them and walk away. I don't like to make a huge scene. When I'm with my guy friends or whatever, I don't care if they touch my bum at all as long as they don't grope me or make it really obvious. They're my friends and they're guys so I understand that they like to goof off and me usually being the only girl (and I'm used to it) I've never really minded when I'm surrounded by the people I trust. I know my friends and I all have a certain level of respect for each other and we'd never break that.

I like it - It makes me feel sexy =]

I'm Ok with it. I am a "hands on" person. Example would be while telling a story to someone, I touch their arm or hand. So if it is innocent, no biggy! Now grab a handful of breast or butt without my ok first, then I have a problem with it!

I don't like it when guys I'm not really cool with feel comfortable groping my ass like at a party or in a club. That's not cool. But if I know you and we have that kind of flirtatious relationship then it's cool at certain times but there is a time and place for everything. Don't grab my ass on the bus when there are a bunch of other people standing around.

I'm not, I need a good connection with the person, first

Eeek, no. Had that sort of thing happen to me before w/ I guy I totally did not know. Yipes. He gave me his # and - believe me - I did not call.
