I’m a 16 year old male and have been noticing lately that my urethral opening is getting larger. This may be due to masturbation but I’m not sure, and for years I have had the unsolved issue of pain or discomfort when I pee. I want to go to a doctor now but have been dealing with it silently as I’m apprehensive about telling my parents. Could an explanation for my urethral opening getting larger be a swollen urethra, or just too much masturbation? Also is this change reversible as I don’t want it to end up being disfiguring. Thanks a lot for reading!
