Hello, my name is Celeste, I am 17 and just notice that I have a lump, the size of a cherry on the posterior wall of my vagina. It doesn't hurt, just annoying that there is something there. I have had some abdomen discomfort. No bleeding. I think it's from using a rough object to masterbaiting. My boyfriend says it is new and noticeable. Please tell me you thoughts on what thus mass could be. You can email me for other questions YYYY@YYYY
