The Twenty-Nineth Canto contains our first little smidgeon of sex. Granted, nothing more than “lay with” and “begat.”
I’m reminded that Pound, despite his exhortations to others to “make it new,” had a conservative streak running through his poetry (read his older stuff -it’s pretty traditional). Despite this, we do see some avant garde and experimental streaks running through this Canto.

And wasn’t modernism supposed to usher in the sexual revolution? He was radical enough to be a littérateur/Nazi, but nothing more than begat after laying with erotic verse. Perhaps this may be of interest:

Just the sound makes me want to pack up and move to Greece. Too bad their economy is in the process of collapsing.
Look at post-modernism, today’s version of the avant-garde, which is considered to be a conservative movement.
Or look at T.S. Eliot. Artistic innovation need not be sexually adventurous, as well.
Indeed, colour me Freudian. I love exploring the sexual side of nature, a true source of subjectivity.
