We are not sexually free. All sex between consenting adults is not legal. I favor legalizing human sexuality. It should be very simple. Any kind of sex is made legal as long as it's done in privacy and all involved are consenting adults. End of story. It should not matter whether they're of the same or opposite sex, if money is involved, if some people think the acts are strange. If they consent -- if they're adults -- if it's in a privacy, it's legal.
Btw, strong emphasis on adults. No pedophilia is allowed.
