I am male and 23 years old.  I did masturbate while in college up to now, so about 5 years.  I masturbated 3 weeks ago and noticed sores or blisters on my urethra by the opening of my penis.  I went to the doctor and had a blood test and urine test done both whicChatDoctore back normal.  I was told by two doctors that the blisters were due to my masturbation and it would heal on its own.  They said the ejaculation caused irritation to the urethra.  I know the urethra is a sensitive part to the body, but how long would it take the heal on its own?  I wouldnt say they are blisters, more like bumps or sores.  Is there anything I can do to help it heal?  Should I be worried at all?  Is it normal for the body to respond like this to irritation with these sores? I dont have any pain urinating and I dont have a sense of urgency to urine.  The sores do hurt a little but they bug me more since I can feel them and it is discomforting.  Thanks for the help.
Good day, and thank you for being with Chat Doctor ! It would take around 2 weeks to heal completely with adequate rest and nutrition. Please avoid ejaculation for two weeks while there is still pain and let your body heal itself. I hope I have answered your question satisfactorily, and please consider a 5-Star rating for my answer. Thank you very much.
