Several weeks ago I met a guy and I'm really attracted to him physically. We also have good emotional connection. He's really handsome and experienced in terms of how to make a girl special etc. We had several dates, we had a really good time together, but we didn't discuss our relationship yet and being exclusive to each other.
And everything goes to sex, I'm really afraid to get hurt after sleeping with him cause I know that he likes playing mental games, chasing and after sleeping with him he can lose interest.

We don't really text each other between our meetings and I feel he's not ready for something serious. So how can I discuss with him my feelings without scaring him? And how much should I wait before start trusting him if he's not just playing with me?
