Several hours after having unprotected oral sex performed on me my groin area felt like it was stinging/burning. My testicles were red but it could have just been because of the heat of that day. That lasted for about a week. A week later there was a bump on the shaft at the top. Though not big, it was noticeable. There was also a burning/stinging sensation on the side that later had a small bump. These have gone away thanks to Tinactin. Now the tip of my penis stings at the opening of the urethra. It doesn't bother me when I urinate or after a while if I put ointment on it. Hydrocortisone helps with the stinging for a while and so does Neosporin. It's hard to look, but there is a black lump/cold sore looking irritation just inside my urethra on the left side. Using a light I was able to tell it is actually a bunch of small black lumps. Planned Parenthood hasn't got back with me on the test and they said that would be a good sign. The doctor also said it could have been an allergic reaction to something about the women or it was just created in my mind. At the time I didn't notice the black lumps so couldn't bring it up. This burning/stinging sensation at the tip of my penis has been going on for about a week now. Do I or don't I have a STD? Thanks for any help.
