<s>[INST] ive been having unprotected sex with my gf of two years and shes recently had a uti and we may have fooled around when this was present. the tip of my penis was itching for about a week now when i get an erection i feel a stinging pain down to the middle of my penis, its definitely the urinary tract. [/INST] Hi,It may be balanoposthitis with urethritis. Consult the dermatologist for the perfect diagnosis. After thorough examination and investigations.. he might give proper treatment. Drink lot of water. Keep the hygiene good. Antihistaminics,antibiotics and antifungal therapy may be considered.Hope this helps.Dr.Ilyas a Patel MDDermatologist </s>
