What Causes Red Bumps On Penile Shaft After Masturbation?

Question: I have been tested for herpes multiple times. Each time came back negative. However, sometimes after masturbation I get a single red bump on the left side of my penis shaft. I was treated for syphillis in August, and it's near to spot that I had a chancre. Even though I tested negative for herpes, I still was prescribed valtrex. No pain. No itching. And it doesn't even look like a herpes blister. Not an ingrown hair either, I don't have hair there. What could it be?
