Women has menstrual cycle, while men don't have. Their sperm will build up over time, and if it is unreleased, the testicle will explode from the pressure of too many sperm.
hence, men have to whack off.
there are some guys who don't dare to whack off, and thus, their balls explodes.
Thus, rise the origin of the phrase, "you have no balls", which means you are a coward.
.............. -.-
When the sperm are released, sometimes, more would be released from the right ball or more from the left ball. But it doesn't really matter which ball releases more, as long as the sperm gets released.
Thus the phrase: "LP, PL"

pruss one?
WT....
You have no balls? If you have no stick, how?
