Hi, I recently had sex with my boyfriend and something really weird happened. It was very deep sex and I finished pretty fast but right after I finished my boyfriend was pretty much stuck. It felt like there was something deep by my cervix that was stopping him from pulling out and if he pulled too hard it hurt. It took a good while for him to be able to pull out but it was still quite uncomfortable then. I personally enjoy it when my cervix is hit during sex as well but this time, right after when I went to stand up there was a tight feeling in my uterus and it was difficult for me to stand up straight. It went away after two minutes but I have never experienced anything like this. Any ideas?
