He sounds incredibly sketchy. Like sketchy as in creepy. It's going to be hard to hear this, but I would get out of there fast. Based on how he is talking about sex, all he wants is sex. He doesn't really care about you emotionally, not to mention that if you are under 18 and he is over, that is considered pedophilia.
This is a clear sign of what I call "pervy sharks." Pervy sharks find their prey and compliment them excessively, eventually leading the conversation to sex. They'll say anything from "I love you" or "You are the best" and such. Girls often get very confused signals from them because pervy sharks never connect emotionally. They only focus on physical. And, once you've had sex and such, they leave and you are left heart broken and used.
If he really truly loved you, he would be worried about you when you had a problem and wouldn't be trying to get you to have sex. So I strongly suggest you stop talking.
Tl;Dr; As my friend would say, he is "bad news bears" and it sounds like he doesn't really love you.

If he's saying all of that stuff when you haven't even dated, yes he is a player and is trying to get you into bed. People don't start talking about that stuff typically until they have been in a relationship for some time. Depending on your age and the age of consent in your state, it could very well be illegal for you to sleep with him anyway.
