So today my boyfriend and I had sex , and he fully nutted in me he didn't pull out at all. After that I started having horrible stomach cramps kind of like contractions coming and going sharp pains but for some reason that sharp pain turned into farts. And then after that I had diarrehea. This all happened in 2 hours. Has anyone else had this
