I am 37 year old unmarried male; I have habit of frequent Masturbation. My problem is that if I donâ€™t masturbate for long say for 48 hours my area around testicles starts paining along with back pain and sometimes scrotum gets swelling. In such condition if I masturbate and once the fluid is discharged, slowly my scrotum/testicles and back stops paining. My position of masturbation is a face-down (prone) position. Please do advice in the matter. Kindly acknowledge. Thanks.

This has to be psychological. There is no medical logic to explain this type of pain. If you are thinking that pain is because of collection of semen in testis then let me tell you that in such cases person gets nocturnal emissions (night discharge). Moreover testicular pain referred to abdomen (your tummy) and not to your back. One of the two things you can do, ignore the pain (pain is not so severe, I suppose) or masturbate (which is not going to harm you so far it is not becoming your compulsion).
