For some reason, this relates in my mind directly to this quote from a Peter de Vries's novel Wtich's Milk:
"He said that the English vocabulary for sex was hopeless, very nearly all down the line. There were only coarse words on the one hand, and, on the other, the bookish ones, hardly less embarrassing. There was nothing in between, nothing really and honestly usable for two people... For every organ or act for which a foul or stilted word was the only existing alternative, he tried to think of a suitable one, from the phonetic and other standpoints."
