I’m so anxious

I’m so anxious right now. I was with my ex for a long time and he was the only person I slept with. The other day I slept with someone new for the first time. Everything was fine and he seemed into it. He was on top at first and then we switched and I noticed he wasn’t that hard and I started freaking out internally thinking it was my fault. I was scared he was attracted to me even tho he told me how sexy I was. at this point I felt like I couldn’t ride him bc it wouldn’t work so I paused and gave him a very quick bj which helped a little. He didn’t say anything and neither did I. I felt really uncomfortable and anxious like it was all my fault. When I was riding him and asked to switch bc I was getting so hot he said in a second bc what I was doing felt so good. Which made me feel better. He lasted a decent amount of time before finishing and towards the end was making a lot of noise and saying it felt good. He even went back in after finishing. I guess bc he didn’t get fully hard at points which I’m not use to my ex use to get hard so easily. It made me question if it was me and it made me self conscious. After he seemed pleased and kept kissing me and touching me and even mentioned next time. He also was after alcohol which I know can affect getting it up but I still can’t help but feel like it’s all my fault. I was pretty active made a lot of noise switched positions a lot pulled his hair kissed his neck and chest which he really liked and scratched him with my nails. I also have ocd and I’m really overthinking the whole thing. He snapped me the next day but we haven’t really texted a lot anyway in general but he sent me pics of the marks I left on his chest.
