choking then fainting and peeing

So me and my boyfriend were having sex tonight, and he was choking me, everything was normal, and i could feel myself getting a little light headed (normally if its too much i’ll tap his arm or whatever body part i can reach and that’ll be his cue to stop but it never got to that point where i felt i needed to). Without even realizing it i passed out, he immediately stopped and tapped my cheek a few times because he wasn’t exactly sure how to wake me, and when i came to he tried to keep me calm and made sure i was okay before we got up. I cried a little because i was confused and obviously a little freaked out by it, but all in all i felt fine, just very exhausted. When he was making sure I was okay he was telling me what happened and apparently when i passed out i started convulsing for a few seconds and thats when he woke me up. I also remember feeling like i had been biting my tongue when i came too. When we were getting up to get dressed i noticed that my underwear, my butt, and his sheets were wet and immediately realized i’d peed myself while i was unconscious.

Im a naturally curious person so after we cleaned everything up and calmed down i was looking up fainting and incontinence being related and i saw a few things about how during a seizure its common to lose control of your bladder, convulse, and bite your tongue. Now i’ve never had a seizure before, and i’ve only ever fainted once due to being dehydrated and not having eaten for too long, so neither is a normal thing for me. There is no reason for me to believe I had a seizure other than those three things, and it is completely understandable that the reason i passed out was because i just didn’t have enough blood flow to my brain, but I also couldnt find much on losing control of your bladder during fainting and found absolutely nothing about biting your tongue during it.

I was just wondering if anyone has fainted and lost control of their bladder or anything of that sort as I can’t find much about it on the web, and if it was a seizure, should i be careful about sleeping?

ALSO, we are obviously going to be retiring choking for the time being, and if we ever do that again we will be much more careful and restrained while doing it.
