Hi, it s Randy again...i ve been researching this before I decided to post this question but wasn t too satisfied with the answers I ve read. I m just wondering if you could get cancer from masturbating too much? I well, I ve been told to hold off for week on hand practice, but I ve only waited a few days and other than being a bit sore (probally due to still being sore) I ve noticed these small bumps beneath the stim of my penis, like little bumps -- pimples or something..I ve read that Sometimes when you masturbate a lot or if you have sex with a dirty girl you can have bumps on your penis but they are timely and go away in some time...and I can assure you -- I don t have sex with dirty women. So, I just want another opinion before I go to the doctor . Thanks in advance for reading this.
