So, what do you know about sex (and literature)?

Only Richard Allan Cooper was brave enough to guess who said what, so for the rest of you, here are the answers!

Who said this about sex?

A widespread taste for pornography means that nature is alerting us to some threat of extinction.
J G Ballard, "News from the Sun," Myths of the Near Future, 1982

Sex is interesting, but it's not totally important. I mean it's not even as important (physically) as excretion. A man can go seventy years without a piece of ass, but he can die in a week without a bowel movement.
Charles Bukowski, Notes on a Dirty Old Man

The tragedy of sexual intercourse is the perpetual virginity of the soul.
William B Yeats

My reaction to porn films is as follows: After the first ten minutes, I want to go home and screw. After the first 20 minutes, I never want to screw again as long as I live.
Erica Jong, Playboy Magazine, September 1975

The good thing about masturbation is that you don't have to get dressed up for it.
Truman Capote

"The majority of husbands remind me of an orangutan trying to play the violin."
Honore de Balzac

Sex and beauty are inseparable,
Like life and consciousness.
And the intelligence which goes
With sex and beauty,
Is intuition.
D H Lawrence

In itself, homosexuality is as limiting as heterosexuality: the ideal should be to be capable of loving a woman or a man; either, a human being, without feeling fear, restraint, or obligation. Simone de Beauvoir

Lesbianism has always seemed to me an extremely inventive response to a shortage of men, but otherwise not worth the trouble.
Nora Ephron, Heartburn, 1983

My instincts are all against a woman being too frank and at her ease with me. It is no compliment to a man. Where the real sex feeling begins, timidity and distrust are its companions, heritage from old wicked days when love and violence went often hand in hand.
Sir Arthur Conan Doyle, The Lost World

I've mostly written about sex by means of the space break.
Barbara Kingsolver

And many congratulations to Richard, who got two answers right - bravo, sir!
