The spanking fetish is very prevalent in the gay male world, I find, even outside explicit fetish circles.
I know a couple of erotic writers who specialize in writing stories about young men being spanked or caned by their boarding school teachers. Apparently there’s a living to be made. ;-)
I’ve occasionally taken the spankee role and less occasionally been the spanker, and I must say there can be a serious erotic charge.
How interesting to see how far back it goes!
I didn’t know about that fresco in Pompeii. Amazing to see it.
