yes, they like you
No, some guys may not be "excited" by a girls chest, for example: gay guys.
Some do. Some don't.
it depends on the nature and likeness of the boy
Just let them have their fun you fags
I love it when women do that. It is one of my all time favorite things.
cuz it makes them feel good and plus they like to touch girls bums
Some guys do this because the girls chest bounces when they laugh, other guys just like to hear their girlfriend or crush laugh - period.
I think because they like each other or they are sexic
depends on the girl and where you're looking. most girls like guys who look into their eyes or at their face, but they dont like guys looking at their chest/breasts, butt, and sometimes hips or stomach. but like i said, it depends on what kind of girl it is, but girls don't necessarily liked being looked at by their "body".
Because some guys are like this and believe in cheating and that it is ok to flirt and look but not touch
Men are stimulated by visual and tactile sensation, so they like to look and touch.
Don't flirt with him and don't touch him. Eventually he'll get the picture..
