Does he just like me for sex?

So I’ve been talking to this guy for about a month now and we’ve already had sex 3 times. We always have have a good times the few times that I’ve seen him and he’s so nice and the sex is amazing, but sometimes I feel like he just wants me for the sex. He’s not much of a texter so I tend to initiate the conversation but when we see each other he’s super talkative and is all over me. So I don’t know if it’s a good idea to ask him if he just wants me for sex or if he actually likes me?? I’m starting to really like him and I don’t want to get lead on a heartbroken. Idk what to do help!!!
