Need advise please !

So there’s this guy. He kissed me a few weeks ago out of the blue and we have many mutual friends that we are both really close to. So we kept the hooking up between us. We have just started to become close. We spent a few nights together and fooled around but we didn’t have sex even though he’s made it very clear that anytime I’m ready he’s ready and has been quite pushy but I haven’t let it get there. But when we talk before we sleep or whatever he talks about sleeping with other girls and how he can’t wait and asks me things like if he wears this and I was a random girl, would I sleep with him. I personally find it quite disrespectful but then again he owes me nothing I suppose but it does upset me. I have hinted that it annoys me or I just keep quiet or play it off as a joke but I’m not sure if he’s being serious or not. But there’s still a really soft side to him but he just doesn’t show much effort towards me. He kind of uses me for the fun stuff or for help with college but I feel like that’s where it ends. In the beginning I told him I’m not really the type to hook up and I told him I know if we did have sex he’d piss off and I’m just not like that but he told me no he’s not like that and he’s not with multiple people at once. But now he denies that and says no he has been with multiple girls and that’s what he does but I am not sure if he was joking or not. Just beginning to feel disrespectful and used. Am I being sensitive? What do I do ? Please help !!
