because is an arousal mechanism.now, I do that on girls that I'm dating and if they let me do that then I know I can go one step further; on gfs I do it cause I know they enjoy it.
I guess it's just after a certain point in a relationship we pretty much feel the stop sign is down & we can touch here or there. WHY? We like bottoms almost as much as we like chests too.
umm because guys know we love it. duhh
yeah like briekittie said. they know we like it! my guy does it to me all the time.
My boyfriend touches between my legs while kissing me
My guy likes to rub my bottom while kissing me.why guys like doing that? lol but I must agree, I love it:$ hehe
