I was going to answer, but it's already been taken care of. If he's already gotten between your legs, he's satisfied and has nothing else to hunt for. The "game" is over and he won. If he's not contacting you, he just wanted casual sex/conversation and nothing serious. It's cold and he'll more than likely contact you again if he enjoyed the sex and time you two spent but if you want more, your best bet now is to just cut your losses and move on. He's probably not committing to you. Or you can keep it going on a friends with benefits tip, but we all know how that plays out in the end for most women.
