Hi, my boyfriend and I was having sex and after I stated to get a bump on the inner part of the lip, over the next few days it s just getting bigger and bigger, and I touched it and it popped like a cyst. The bump went down, so my boyfriend and I had sex again, and the bump has reappeared. It only happens when he s rubbing me really fast. Can I use Polysporin on the area, or go back to the doctors? Now I just been to the doctors 2 months ago and got texts done, and I m clean. So what is the bump? YYYY@YYYY
