Well I was wondering if some one could help me. Me and my girl friend have been togeather for 2 years and that is the only person i have been with sence. Same with her, but one day i noticed a pimple looking thing on the under side of my penis. I poped it about 4 days ago and now there is just a mid size red bumb but only one. it does not itch really or not that sore but it is still there and i am scared i to think i might have herpes. keep in mind me and my girl friend have been faith full, is there any othere way you can get it?
