Like most tortures, the basic concept is very simple: it hurts to straddle a thin or pointy surface. Right? Even a piece of couple pieces of lumber, as in this picture, are clearly very uncomfortable to sit on.
There ought to be some kind of public outreach agency where, if you have a gorgeous, gorgeous naked boy as your prisoner, someone comes over and shows you how to tie him up properly. Dang.

BDSM has existed in Japanese sexual culture for a long time, but what kinky Westerners like to consider “the Ancient Art of Japanese bondage” probably dates to the 1980s and is largely from San Francisco. Japanese SM magazines and “pinku” movies like this attest to this point: as recently as the 1970s, no one in Japan seems to be able to tie a decent knot, let alone do all the fancy rope-work that these days are given Japanese names. Before that, it’s fairly hard to find Japanese bondage erotica.
(Chris Foss, 1972) This is one of the illustrations from Alex Comfort’s original Joy of Sex, complete with the guy who is famously called a “werewolf with a hangover.” Comfort’s book was groundbreaking in lots of ways, though it doesn’t have much to say about kink (Or anal sex. Or gay sex. Or lesbian sex. Or….)
Probably for its shock value, this illustration was one of three reproduced in a 1974 edition of The Whole Earth Catalog, by then a staple reference work for the counter-culture. Undoubtedly this became the explicit sexual bondage image most frequently viewed by people who were not seeking out explicit sexual bondage images. I have twice seen it cut out of library copies of the WEC, though whether by censors or collectors I don’t know.
Given its wide circulation, it’s a shame that he’s doing it wrong. Where are his knees going to go?
