I have been seeing a new guy and we are constantly kissing each other. If I am laying next to him I automatically kiss his chest over and over again. I don't even think about it, I just do it. I know i have felt this way in the past with other guys.

But then I know other guys I have been with I did not do this. It was almost as if I had to think about it first "oh, I guess I should kiss his chest".

Is this a sign I really like this guy, or more of a sign that I am just physically attracted to him? He seems to do this also to me.
