Take mental notes on his actions and manner of speaking. Guys/girls who only want sex will rarely care about how you feel or, in some cases, how you look. Try throwing some curveballs in the mix to test him.
Now, be aware that some people are just very sexual; just because they talk about sex a lot doesn't mean that's all they want. I know a girl who is very open about it and talks/jokes about sex and sexual topics often, but loves her boyfriend with all of her heart. So you have to do some homework to know whether he is just a sexual guy, or if he really only wants sex.2
