drunk question

I was very drunk last night and so was my partner. We had sex and I was very surprised how hard he got even when he has a lot of alcohol in him. We started to have sex with a condom but we eventually took it off. We fucked for a little bit then I just gave him a blowjob at the end. I don't know if it was cum or not because I was drunk but he mentioned that while he was cumming it felt like he was going to pee too? Idek but like he came in my mouth and I swallowed and for a little bit he was still hard. What is this?
