Hey! I am 20 years old and I am experiencing this problem since a week. A week back I experienced burning sensation after masturbation for 20 mins, somewhere in middle of penis. Later I stopped it for a week and then I experienced pain in my lower abdomen, after two days it vanished by itself. After that I tried masturbating then I had some irritation in the penis. Is it normal or shud I consult a doctor? According to my observation I experience burning sensation only after masturbation. Which is usually in the pipe through which the urine is excreted.
