Literally impossible to say with any certainty. You were friends with benefits before, so it may be that he's looking for no strings sex again. It may be he isn't, and genuinely does want to catch up. Either way there is no way of knowing until you actually see him, and either ask him or he makes his intentions clear. If those intentions align with yours, then great. If not, then walk away. It is worth noting, though, that most people have sex with people that they like, both physically and to spend time with. It's very unlikely that he 'likes you for sex' and doesn't also actually like spending time with you. What's important is that what you want in that respect is the same as what he wants. There is nothing wrong with two people spending time together and having sex but not actually having a relationship outside of that. It doesn't mean he's using you, or disrespects you, or doesn't like you. It just means you're two people having casual sex, and that's fine. But that's not what you want anymore and it's still what he wants, just don't do it. If you're unsure what he wants, ask him, being aware of course that it's hardly unheard of for men to lie about that sort of thing to get sex, but it will at least give you something to go off and I'd hope that you can spot a lie given that you do already know him. But communication is important if you're sleeping with someone even if you're not in a relationship with them. So if you're not sure whether you both want the same things, talk to him about it.
