<s>[INST] Hi, i am a male and about 6 months ago i had a relatively intense sexual experience with a female. To specify, we went on and off for multiple hours. After about the fourth or fifth hour, i noticed a red “scab?” on my penis. The sex was unprotected. Six months later, I see no progress on my penis healing. I have been tested for STDs, all negative. I have used Hydrocortisone, Cetaphil, Neosporin, Vaseline to no effect. It seems to get more red with masturbation or sexual activity. The bottom of the “scab” is reddish, while the top has a yellowish color. I just started using Hydrogen Peroxide, followed by Vaseline, and I cannot tell if it is getting better. I shower often, wash my penis always, and do not wash with soap, as warned by my physician. There are times where it is extremely red, and times where it looks brownish. It is very shiny, and it cannot be peeled or picked at. Again, i would like to stress this was noticed a second after taking my penis out of the female. I have had no luck online. Any and all help is appreciated. [/INST] Hi, It may be a superficial bacterial infection. You can apply topical antibiotics like Mupirocin for symptomatic relief. If symptoms persist, better to consult a dermatologist and get evaluated. Hope I have answered your query. Let me know if I can assist you further. </s>
