Hi, i am a 23 year old male and about 3 months ago I was fooling around with a girl, nothing sexual happened but there was dry humping and after that occured i notice a red rash on shaft of my penis near the head (I am circumcised) I figured it was just a rash from rubbing up against my jeans, and i would put lotions on it to try and get rid of it, this did not work.
The redness will go away if i were to leave my penis alone, however if i am to masterbate it comes back even worse and has even formed a small red like blister (a single one). So I decided not to masterbate and see if it will go away, and after awhile the redness went away (the redness would sort of flake away) but a small whiteish coloured bumplike thing UNDER the skin would remain. Worrying this was HSV I went to the local walk in clinc and got STD testing done (urine and blood). I told them about the the mark, and the nurse looked at it (the white bump) and said it didn't look like anything sexually transmitted.
I went to get the results today and everything came back negative, and i really have no idea what this is or what to do. I havent had sex in over a year, but have had unprotected oral sex over 6 months ago. It kind of tingles and will still form the redness whenever there is any friction. Any help with this would be greatly appreciated, thanks.
