i made a girl cry during sex

This happened couple months ago and it is still bothering Me to this day. For the record, i totally regret this and wish I never done this, but i never could’ve guessed that this Would happen. I had a two week relationship with this girl who was Incredibly sex driven, all she wanted to do was to get Intimate. At uni, at my apartment, at her place, in public, it Didn’t really matter to her. And every time we had sex she Wanted to try something more and more intense. We pretty much did everything in the book, and on the Second week she literally wanted to black out from a Deep throat. I was really uncomfortable with that, but she Insisted, so i just rolled with it. For the first 10 minutes she Couldn’t bring herself to commit to it, every time she got Close to blackout, she just backed off, so she asked me to Forcefully hold her head, while she was doing it. couple Times i let her go, cause it was seriously messed up, but On a final try i didn’t, because she got angry at me, and As she was blacking out tears started dripping down her Face and just like that she was out. When she woke up she just started crying, crawled up on Bed and started to whisper stuff to herself, while she was In tears. That was the end of it, the day after i ended things and Told her to get some professional help, cause the way she Was acting wasn’t normal at all, it seemed like she was Trying to avoid some trauma through sex and i hate that i Was part of it.
