I don't know how I should describe this. Since the past one or two weeks I am getting some weird feeling in my testicles. Like something is scratching from inside, or how you see water boiling kinda thinggy. Its difficult to explain but this is the only way I can think of putting it through. I am not having any sort of pain or any sickness whatsoever. Is it happening due to excessive masturbation? I do it like twice a day. I have been doing a lot in the past too but never faced anything like this. What could be the possible reason this?
