I CAN DO THAT. but just a lone kiss on the hand, floating in the interaction with no kino-context doesn't really work. It will seem like something you are just doing (oh he decided to kiss my hand. He's probably been doing it to women all week) instead of something you are. So you gotta anchor it in other touching, move the kisses up her arm until she jerks away, or reach up and put your arm around her.
maybe it's just because I'm the absolute f*c*ing man and I'm often percieved as being ****y and mean, and a fighter and a dog and a womanizer and a bully. But when I kiss a woman's hand, especially with any kind of social proof, people say things like "oh it's on now" or "watch out for that one." which generally helps or at least gives me an ego boost.
