I thought that girls when girls orgasm they cum? Maybe it was just gas.
You been watching too much porn player. That cum in those videos is actually pee. Yes, it's piss and it rarely happens in the outside world as per my experience.
I had a girl send a stream of it up my chest once when I was younger and she was as surprised as I was. If a girl has weak bowel control that is what happens. When a girl actually cums you should be able to smell the difference in the air if you have a decent amount of experience with her.
Similar to the ambience of fart in the air of the bedroom when you backdoor a chick for the first time. Hope this helps
