Hi im 17 years old and have been sexually active since 14 with the same guy.Neither of us have any stds,and sex is always enjoyable. I masterbate about once a week. I know how to make myslef orgasm, and when I orgasmed tonight it was one of the deep sensation ones.Everything was fine and normal like always, but when I got up my uterus hurt and it still does 10 min after. Could I have maybe been pregnant and hurt it cuz I went pretty deep down.I went to deep one time during it and it hurt to but it went back to feeling good.
