So I’ve had this for a while now, basically there’s this big spherical ball next to my right testicle, it’s bigger than the testicle itself, it’s firm and it’s spherical just like a ball, I can push it into my groin, and slightly move it, sometimes it’s there and sometimes I can’t see it. I’m afraid it’s some sort of cancer and I’m worried,
FYI: I’m 17 and never had sex however I do masturbate
