Age:20, Gender: Male I have had pain for over a month from masturbation. It cannot be an STD and a CT scan returned nothing meaning it cannot be prostatitis... I have had a urine test which returned nothing and had a physical exam for prostatitis which was thought to not be of concern (regarding prostatitits). I did have brown semen once but after a course of antibiotics, that has cleared up. I would often masturbate through abdominal workouts which caused me to have a groin strain. That, however, healed up and following that I would only masturbate the normal way. However, by this time any arousal/ejaculation I would get abdominal pain. Initially the abdominal pain healed up within a week but now has lasted for over a month. I am now refraining from any and all ejaculation/arousal though things don t seem to feel any better. Please let me know what this could possibly be?
