Am I a rebound?

The guy I'm seeing came out of a 3 year on and off relationship 6 weeks ago

He says that the relationship would've only been a few months in total but it was over a 3 year period

He's kissed a lot of girls so I'm guessing this was during the breaks in his relationship , which to me indicates he rebounds( he's only 19) hasn't had that much time to kiss a heap of girls beforehand lol

We started seeing eachother about 2 weeks ago and we've just clicked , we have common interests and he's very caring and fun. He was a real gentlemen and says he wants to stick around, I've asked if I'm a rebound and he's said I'm not but I've told him I wanna give things a little more time before we're officially going out

Things have kinda fast forwarded in the sex department but we haven't had sex and I've told him I wanna slow down and I've been given permission to slap him if he gets too horny lol

What should I do??
