Hi, may I answer your health queries right now ? Please type your query here...i have a knot that came up under the skin on my penis about a month ago. it was sore but it really did not bother me . i just thought it happen while having sex. i ask my wife if there was a way that if your penis could be broken? she stated yes. tonight while taking a shower when i was washing it was alot sore and felt as if it was getting bigger . this really has me worried . i am not discharging or anything of that . it hurts the worst when i have a erection.
