There’s a connection, or an alleged connection, between the reddened ass of a freshly-disciplined submissive, and the strong sexual response of doms to that reddened, swollen sexual area, and the bright red, blood-swollen perineal swellings in bonobo and chimp females.

This is a young bonobo female up in a tree, flashing her perineal swelling. (Male bonobos looking up at her ass not shown.)

“Perineal” means that lovely, sexually sensitive skin from the vagina to the anus. When it swells up in bonobos and chimps, it becomes extremely, er, noticeable. 

Fact is, if bonobos could speak, they still wouldn’t have a word for “decorum”. 

So the idea is that we doms, at least those of us with a taste for a freshly-disciplined girl or boy, are drawing on some powerfully atavistic urges from way back in our evolutionary ancestry. 

In chimps and bonobos that swelling occurs at oestrus, the point in the menstrual cycle when the female is most likely to reproduce and to want to do a lot of fucking. 

That red and swollen genital and buttock signal, that the female is receptive and interested, gets an extremely strong reaction from the males in the troupe. They’ll hang around her, trying for any sexual opportunity they can get. They’ll fight over her, or – if they think they’d lose a fight – they’ll wait until the dominant male is distracted, and nip in for a quick fuck before he notices.

By the way, her strategy isn’t to mate with the most dominant male. Her strategy is to get a lot of fucking done, with lots of males. The males who fuck her feel good about her, which is handy for getting food and protection and so on, and when she gives birth they’ll be unlikely to kill the offspring. Since it might be theirs.

(By the way, almost everything people say when they use terms like “alpha male” is complete, utter, abject bullshit. Especially if they apply those terms to humans, and especially in the highest, forever and ever, if they apply those terms to themselves. The only exception is the first sentence of this paragraph.)

Spanked girl with her ass up. There’s some sort of sexual signalling going on here. I think.

Humans are different from our chimp and bonobo cousins, though. Human girls don’t get that red ass thing.

Yeah, you’re thinking, “Ah-hah! Except for submissive girls who’ve been bad, and submissive boys, too.” You’re way ahead of me, but there’s more to be said about this. For example, “is this theory actually true?” 

Well, we’ll have to get to that tomorrow. Tune in!
