i'm wondering if anybody has any experience with blacking out / losing your memory after having sex on md?

last week i took 2 caps and had a couple drinks (not many - maybe 5 standards max). i remember most of the night, except my girl and i apparently had sex twice, at 2 seperate times, and i have absolutely no memory of this happening. like i remember most of what happened before, between, and after, and i know that i was awake and conscious for the entire night, but i had absolutely no idea that we'd had sex until we were talking about it the next day.

the strange thing is, this isn't the first time this exact scenario has happened to me. about 2 years ago, with a different partner, i had the same experience, where we apparently had sex while we were rolling and i had absolutely no memory of it, even though i remembered the rest of the night.

i'm wondering if anybody has any similar sort of experiences? i've done md loads of times over the years, but these 2 are the only times that i've ever lost my memory. these are also the only times that i've ever gotten freaky with someone whilst doing it. i feel like this can't be a coincidence? is this like a common experience or something?

it's honestly really unsettling to not be able to remember something so private. like i have no idea what happened or why my memory of these specific moments is so grey. it's a really vulnerable feeling. any thoughts or advice are welcome
