hello. basically when the end of my penis is rubbed when i am erect, it feels good for a moment, builds, and then suddenly i start to urinate for a while. this happened in oral sex when the end of my penis was rubbed in the same way/place. what on earth is wrong with me? i am very worried and would really appreciate some help doc...it is definately urine, once it starts happening i can then pee as normal. only way i can ejaculate/orgasm is by keeping the foreskin over the head...otherwise i always urinate... help me please. thanks
