The answer is a male dominated society. The female genitals have become a taboo subject in language: we can only speak about it in clinical terms or cute euphemism, and everything outside that is a dirty, nasty word that is used either in dirty, beautiful sex or the worse kind insults. It's a scarce commodity in erotica, though popular in porn, and it's power is so much that people will lower their opinion of you if you use it. The reasoning behind this is based in the reasoning of a conspiracy, which exists only to denying females a strong sexuality and position of power within global decision making. The origin of this conspiracy is found in the Vatican, or as many know it, That Old Boys Club. In TOBC female sexuality is seen as a dangerous thing, though their reasoning appears to be based off rolling the bones of Jesus' dead hands. Those hands that, it is said, wanted to touch the cunt of a woman, but couldn't, and that desire lingered and festered as something unpleasant, deep within the bones, a resentment that built upon the power the woman held over Jesus.Thus the latent desire of Jesus has spread through the Popes who have rolled those bones to divine the future, and since they have set the orders, the hate has spread out like a virus into the minds and hearts of Christians everywhere.
Cock, of course, is fine to say. Males can say anything they want about their cock (including giving it different names). You can even have an anthology called Cock.
The amount of letters you can use in the answer box is due to my laziness. I simply didn't change the quota. See, occasionally there are huge conspiracies designed to take away your freedom of expression and, other times, it's just because there's just some lazy fuck in charge.
