Too bad Americans are programmed to think sex = bad.
Our "Puritan heritage" is still with us... unfortunately.
They were Calvinists who were kicked out of England.
Why were they kicked out of England? Oh, they started a civil war and killed the king and imposed a theocracy. Oliver Cromwell led them.
What were they doing in England?
Oh, they were kicked out of France.
Why were they kicked out of France?
Because they took over a whole city and imposed a theocracy. Citizens had leave a window or door open at all times, so the morality police could keep an eye on everyone to make sure they were doing anything "bad".
What was the penalty for the slightest "bad" thing? Death. Usually by burning.
What was the penalty for the slightest "bad" thing among the Puritans in the New World? Often times death, sometimes by burning. Yes, people were burned at the stake in the New World.
So who started the whole Calvinist movement?
John Calvin.
Who is strongly influenced by the Calvinst strain today?
Southern Bapists, Presbyterians, Christian fundamentalists, and a strongly-fundamentalist movement called Dominionist Theology, or Restoration Theology, which aims to establish a theocracy in the U.S.
Because of all this interwoven into American thinking, we as a culture are twisted up in guilt about sex, even as we fantasize about it.
