I'm 19 years old and I have pain in right testicle from last year. I don't know what is reason behind as i'm single and just do masturbating for some time to avoid night fall as I use to take healthy food. The main thing is that for example i'm okay now so if I do any activity which is related to sex so the pain started its not much painful but irritating a lot and high when I sit on chair or in position like chair. I also would like know the reason of it.
