Happened to me at the party the other night...my butt was grabbed and my wife's also...she just just said...you live with it and I kind of had the same attitude since it is a party and people are a bit drunk and acting silly. The breast thing also hppened, a GG asked how I filled the cups and I said foam padding, she said, can I feel? and a said sure, but when she touched them, I said, 'now I get to feel yours?'....didn;t happen, but she got the point she was polite to ask. I could have said no. It is an odd situation, but I figure if it is done in a positive way, then you might as well be nice and let them...apparently woman do ask stuff like that even to GGs...its all part of the we're on the same team attitude.
