Idk how much info I need to include for this to make complete sense. I'll try to keep it as simple as possible as to not ramble.
So the other day I was at my fwb's place. We don't always have sex when I'm over, sometimes we just cuddle and sleep. But we decided to have sex, which unfortunately didn't last very long. I was gonna ride him, and I started sliding his dick in my ass. I felt a little pain, it wasn't too bad, but I started getting light headed. I got off him and flopped onto the bed next to him, and after a couple minutes I passed out.
I just remember realizing I was dreaming and waking up to see him looking worried to me, he gave me water, and we ended up just going to sleep after. We talked about it the next night, I explained what happened and he said he was worried cause I was making sounds apparently lol. But it ended up all fine.
Anyway I'm not exactly sure what to do, if anything. I had heard stories of passing out from anal before, but it was usually in a context where it was unexpected, like going in the wrong hole on accident or something. In this case, I have experience although haven't been doing AS much recently. But I was still sliding him in slowly, lots of lube of course. Also no signs of bleeding or tearing or anything, and hasn't hurt since.
I don't know if there's anything to worry about with this, or if it's just a one time thing and I just need to warm up more for next time or something lol. But I wanted to share, and curious to hear if anyone knows anything
