First Grindr hookup. Feeling used. :/

So, today I basically hooked up with a guy 10 years my senior. I've never really topped or bottom before, but I've given and gotten oral. (Sorry for being so forward.) I've never had a BF, before. Just a FWB who didn't know what he was doing and was/is "straight." (He's dating a girl now.) Anyway, this guy told me it'd be reciprocal blah blah blah. He came to my door, and I freaked the fuck out. But I invited him inside, and he came into my room and we kissed for a while. His beard hurt too, lol. Anyway, I didn't really know what to do. So I just went down and got to work. 2.5 seconds later, he says he going to cum, and asked where I wanted it. Idk, I didn't think he'd cum so quick, and it hadn't really registered in my brain what he was saying. (I know, how dumb am I?) So, he finishes, and asks me for a rag or something. I obliged, and he cleans himself off and gets dressed. He didn't really say much... I got nothing from the end of the deal. I thought he'd stay longer. While he was getting dressed, he said it was embarrassing. I asked if he meant me, and how timid I was. He said he didn't expect to cum that quick, and that it'd been a long week. I told him I was kind of in a rush, but we had 45mins at least still left. When he left I asked for his name. He told me it. Then I said we should meet again, he said yeah and to keep in touch. I messaged him back on Grindr, and said it was hot, and he said "thanks." I feel kind of used. I want to see him again though, he was hot. Do you think he genuinely wants to see me again, or was he being nice? I just have no idea. I feel kind of dumb and embarrassed too. Did he leave because he was embarrassed? I also felt like I kissed him weird too, I just didn't expect his tongue down my throat so soon. Idk. I feel dumb. Someone please shed light.
