I am currently overseas for the last year. Last month I found myself masturbating more than normal (2-6) each day, 3 days ago during masturbation I felt a little pain and a sharp pain during ejaculaton. Today, I realize that my right testicle is larger and I still feel a sharp pain when touched.
Besides my right testicle being slightly enlarged and some pain there are no other symtoms. Someone told me that I may have just bruised my testicle and that in time it will return to normal.
