I really didn't know were else to post this so I chose here...anyway I have a small bump on my lip that doesn't have pus or doesn't look like a wart but it stays for like 4 or 5 hours then goes away..what could it be?? It doesn't hurt or anything an it comes rarely Im a little worried I have only had 3 partners so far and one being male(still with the male pRtner). I used condoms with my other two but me and him don't do anal sex. Any ideas on what it is?
