physically everytime. Why? in the begining of penatration it feels like a sharp piercing pain like loosing my virginity. after a few strokes its more enjoyable but a few short minutes later it hurts terribly. To describe it feels like my walls tighten up and more sharp pain. Afterwards there is a lot of soar vaginal pain, and stomach cramps that last for a few hours. I have had this problem since i've started having sex 5 years ago. What is the physical Problem?
