Hi, I'm a 17 yr old whose left testicle has shrunk due to over masturbation. This happened when I was 15 and had typhoid and I decided to masturbate(I was addicted to masturbation). After I masturbated, my left testicle was hurting like hell....almost burning, especially on being touched. And I noticed it had grown much larger than the right one...after my typhoid was gone it shrunk to a smaller size than before......much smaller. That's how it has been ever since. It only hurts if I masturbate more than once in a day....which I rarely do these days, btw. So, is it testicular atrophy or something else? Like cancer, maybe?
