When I was younger I discovered masterbation just by rubbing my penis, I later discovered how to masterbate normally like most people do although I still would sometimes just rub my penis as it felt good. The motion was basically one or two fingers rubbing the urethra area on my shaft. After a few years of this I think I may have messed up my urethra as pee does not always travel straight when I pee now. I might be imagining it but I think my I flattened part of my urethra and therefore injured my penis. Also my penis tends to hurt if I masterbate more than once a day and sometimes even then it still hurts to get an erection. I am very worried and I think I have permanently damaged my penis. Am I right???
