What causes the shaft to sting when touched?
Patient: I masturbated with Cetaphil, it entered my urethra and it's a little more difficult and painful to urinate. My shaft stings to the touch when I press where the head base is. It throbs and stings every now again and when I urinate, and now I can't stay errect. I hadn't had sex 6 months prior to this incident, can I rule out an STI? Doctor: Hello,  You can have acute urinary tract infection or STI. For further work up I suggest you investigate with urine culture report. According to the causative organism and susceptible antibiotic, medication can be prescribed.   Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr Parth Goswami, General & Family Physician
