And, yet, another way to look at what is wrong with humanity.
Think of the lack of Loving Coitus as a thorn in the side of Humanity for the last three millennia. We could never figure out how to get rid of the thorn, so we ignored it. Think lovely thoughts all you like, intellectualize it all you want, the thorn is still there and it hurts. The pain won't go away until we get rid of it. It causes a constant pain that grows over a lifetime of broken intimate relationships and, unlike a thorn in the side, it destroys the self-respect of half of the race directly and the other half through the extension of the deadened life force within the first half.
The best that anyone has accomplished, so far, is to find some other way to share their ecstasy. The pain remains until Loving Coitus is accepted.
