What is blue balls?

its when a males balls ache
and usually occurs after a few days of abstinance
or after being very sexually aroused for a period of time without coming to orgasm
however this is something that he himself can take care of
and anyone who says they can die from it is lying
same goes if they use it as an excuse for sex

Blue balls is a widely used colloquialism describing scrotal pain after high, sustained sexual arousal unrelieved because of lack of orgasm and ejaculation.
