Me or my body???

So there's this guy that I want to start a relationship with. 21, soccer player, built, attractive from head to toe. We hung out twice at his place and he was very nice, and there were some kisses and cuddles... but I'm starting to get the vibe he only wants me for sex. Opens my snapchats, don't reply for hours until I snap him again. The conversations usually consit of sex related topics. Last night he even said, "I want you sexually" what should I do!?? I really want a relationship with him! Is there any way save this from going down the drain??

Also, I want to confront him, but how do I start out by asking if he's interested in a relationship or sex? I'm scared to ask and we get into a fight or something, and he's gone. I don't want to mess up. I really really want a relationship with him!
