I was having sex with a friend last night. She was not under the influence of alcohol (I was) and in cowgirl, she suddenly stopped. She kind of rolled over and laid motionless. I asked what was wrong and she said she was "somehow paralyzed from the waist down." I'm freaking out at this point and then she said it was unprecedented, it "had never happened before. Very strange." After five minutes or perhaps a little less, she invited me back into her vagina where I got myself off out of fear of a scary repeat. Has anyone else experienced this? Have you heard of it?
