Leenia, I beg to disagree. There is something essentially comic about sex, jokes about it exist in every human culture. Indeed, that very perceptive religious writer C.S.Lewis summed up the "incongruous symbiosis" between romantic and physical love as "one of God's jokes."

"In Eros at times we seem to be flying; Venus gives us the sudden twitch that reminds us we are really captive balloons. It is a continual demonstration of the truth that we are composite creatures, rational animals, akin on one side to the angels, on the other to tom-cats. It is a bad thing not to be able to take a joke ... made, I grant you, at our expense, but also (who doubts it?) for our endless benefit." [The Four Loves]
