First off - I was brought up in a strict Catholic environment, so spanking was something fairly common - mostly by school teachers and priests on my classmates and shit. I didn't think too much of it then - just seemed something that was done and I was too young to really contemplate it in depth. A few decades before my time, my old man used to tell stories of "caning" spank practice, where dudes would be left with blood lines and scars. More mature now - the act of spanking seems, 1) pain induction, naturally - but more pertinently, 2) humiliation via someone effectively putting their hands on your ass or touching your ass. Additionally, "you're going across my knee" - seems a fairly typical approach. Putting someone across your knee, stripping them to their bare ass - then spanking them.... I mean, with chicks, I can see it. I have little doubt some kinky chicks like to get down with that shit (share your stories). But outside of this?? Outside of mature consenting males and females? Fuck that. I was in the scouts when I was a kid, and after many years, when I was beginning to grow up like 12 or 13 or something I think - at the end of a camping trip saying fair-wells, the scout leader put his hand on my ass briefly. I had known the guy for years and been on many camping trips led by him, but that was the last fucking camping trip I ever went on with the sick sumbitch. I drew the line right there and then. I knew intuitively - it was necessary to. And all that creeper did was briefly touch my ass. If he'd ever given me a spanking, I can imagine me fucking hunting him down years later.
