My girlfriend had found a lump inside her vagina. What could this be?
Has your girlfriend ever had a pelvic exam? If no, or if not lately, then she should visit her doctor and get checked out . That's the only way she'll figure out what that lump is. The best I could suggest is it may be her cervix . That's the lower tip of the uterus , and it feels like a rounded bump at the end of the vagina . Otherwise, it could be the G-spot, which is located on the ventral (belly-side) wall of the vagina, about 3 or 4cm in from the vaginal entrance. But there's just too many possibilities for what it is, so her best bet would be to just see a doctor.
