MOSTLY 4 GUYS: Why did he stoked my palm with his finger?

Kinda a subconcious thing that most guys do when they are turned on or really like you. I have done that to lots of girls without necessarily thinking ...just wanting to be with them basically. I think it is an instinctual thing though I don't know where it comes from. Doesn't necessarily mean he wants to have , but it does mean something...he wants to kiss you, or cuddle, or something.
