<s>[INST] Hi doctor, I have some kind of allergy on the head of my penis. Please tell me how to resolve it and which doctor should I consult. My age is 25. I did not consult any doctor before this. I do catch a cold in a month or two and I skip my diet many days. I saw this allergy a month ago when my girlfriend got tonsillitis after having oral sex. She said it was because of this. It has still not resolved, I thought it as nothing much and it is in the same manner since then. I do wash it regularly and I use to masturbate too much. [/INST] Hello.
