I forgot to say I use to experience all those discomforting feelings in the testicles but eversince I stop masturbating, I no longer get those feelings.
In my opinion and my experience:
Stop masturbating for like a week. What your testicles are doing is giving signs of need to ejaculate because its used to releasing sperm so often thru masturbation. You're experiencing the after effect. This is why some males say they can't go a day without masturbation, that's because you're used to doing it so often. In order to break that habit, you need to not masturbate for like a week and your body will start to re-condition itself.
