Recently me and my sex partner were really going at it and we became a bit too rough. I went home and took a nap and something just told me to look at my vagina and when I did I seen that the upper hanging part of my vaginal entrance was purple and a bit ripped off. During sex I felt no pain or my vagina even tearing. When I went to pee nothing burned and I didn’t have any discharge but I’m really concerned on how something like that happens and how can it be treated?
