Can masturbation cause small red bumps on tip of penis?
Patient: Hi, may I answer your health queries right Almost a decade ago when I was in the 7th grade, I masturbated for the first   time using lotion. The next day I woke up and noticed that the skin was   darker around the tip of the penis (still on the shaft) and that there was a line   of darker skin along the middle underside of the shaft (aligned with the   urethra). The darker skin was also noticeably looser. I didn't do anything   then, and it still hasn't improved over the past 10 years. I noticed recently   that small red bumps under the tip of the penis have appeared, although they   do not hurt. I tried to pop them, but it's not possible - they are like warts or   something. I have never had sex or had sexual contact with anyone, although   I have masturbated several times a week (on average) for the last ten years    now ?  Please type your query here... Doctor: Hello,  Masturbation is normal, natural and never unhealthy. But the friction associated with hard masturbation could cause some rashes or pain. You need to understand this.  Therefore I suggest consulting a skin specialist for physical examination, diagnosis and treatment.  Hope I have answered your query. Let me know if I can assist you further.
