What does it mean when a guy keeps rubbing your arm?

[Anonymous]

I went to a show with a guy and he put his arm around my shoulder then started rubbing my arm softly at first and after that he kept rubbing faster and faster... what does that mean? I didn't really know what to do?

Maybe he thought you were cold and was making heat? or maybe you were just soft!
A guy did that to me, but I was ignoring him so that's why he was doing it.

It means a) he likes you b) he wants to have sex with you
