I like the wrist thing. It's like a dog showing its belly- a sign of vulnerability.t

okay if we have to be serious here, if I like someone, I'll really lean in to hear what they are saying, and maybe touch their arm as I'm talking back... I think that really paying attention to the conversation is a sign of at the very least a good communication, and that is a real turn on IMO.

sack pinching... lol..
I was gonna tell them if they want to pinch someones' sack, they should do it to their own, in private, and be sure to wash they hands before touching food, lol....
