It seems from what you wrote that you recently met this guy and for some reason you're wondering if his interest in you is only sexual.
One way to find out if his interest in you is only sexual is, if it hasn't already happened, don't have sex with him.
If sex is all he's interested in and you don't do it, he'll notice that and leave you alone or try to pressure you into doing it. If and when he begins to pressure you, you'll know that's all he wants. Then if you don't want to, tell him to get lost, but wait until you know for sure.
