>That is, the idea that a husband may service his wife less often if he gets a mistress is the opposite of what actually happens.

Can confirm, at least for us. Boyfriend and I fuck like rabbits for days after he's been with someone else and then much more frequently than normal for weeks after that.

Yup, certainly looks like it. With red tasseled ropes, no less - very snazzy.

Recently saw a gallery full of shunga - can confirm it's absolutely full of women peeping on couples. Judging from the clothing and hair of all those involved, a few were definitely a husband having sex with a servant girl while his wife peeped on them and schlicked.

>The original experiments with rats applied the following protocol:[8] A male rat was placed into an enclosed large box with four or five female rats in heat. He immediately began to mate with all the female rats again and again until eventually he became exhausted. The females continued nudging and licking him, yet he did not respond. When a novel female was introduced into the box, he became alert and began to mate once again with the new female.

>In Ogi Ogas' A Billion Wicked Thoughts he notes that chimps and goats have dramatically better stamina and recovery times when they get access to fresh females, leading to more sex even with the same old females they've always had access to, rather than less

WOW. This is incredible! It isn't just fantasy, it's science!

This was one of the first pieces of Victorian erotica I ever discovered. It was hot then and it's still hot today. Really helped underline that humans have been complete pervs for a long time.

I recently found what these sort of images may have been inspired by: The shogun and his concubines.

From Mistress-Keeping in Japan: The Pitfalls and the Pleasures:

>Then everyone went to bed: The shogun and his mistress for the night in the centre of the room and a female servant behind a folding screen in the same room. This servant had to remain dressed and stay awake all night. It was her duty to listen to any conversation between the shogun and the girl and to report whatever she heard the following morning. In addition, two other women were posted in an adjoining room to note down everything that happened in the ruler's bed chamber.

>This practice of watching and listening to the shogun go about his manly expressions was for the purpose of proving whether or not the ruler was responsible if his bed partner became pregnant and of preventing the lucky lady from making use of the occasion to present the ruler with a private petition or to engage in political machinations with him.

From http://www.lesleydowner.com/secrets-of-the-shoguns-harem/ :

>When the shogun slept with a concubine, the whole procedure was tightly regulated. First the girl had to be stripped and searched to make sure there were no weapons or notes on her body or in her long luxurious hair. No hairpins were allowed and combs had to be checked to make sure there was no cutting edge. If it was the girl’s first time, one of the old ladies would check she was a virgin. Once she and the shogun were in bed, there would be two ladies-in-waiting lying wide awake in the room, one on each side. Two more listened behind screens not far way, to ensure that the girl did not make any requests for herself or her family.

>No doubt all this formality was as oppressive for the shogun as for the concubine. The early shoguns took to spending a lot of time in the bath, where there was just one cheerful low-class girl to scrub his back. Quite a few children were born to bath attendants and known as the ‘children of the bath’. Eventually the elders put an end to this practice and thereafter the shogun had to bath in the men’s palace.

On a related but sadder note:

>Princess Kazu’s relationship with the teenage shogun, too, was complicated. One lady-in-waiting wrote a letter home, reporting loyally, ‘When the shogun comes into the inner palace, the princess looks after him very well. She is the perfect wife and will soon be granted a son.’ In reality Kazu never had children and even refused to see the shogun off when he went to war. The day before he left, however, she gave him a present of a concubine, to ensure he had a son and heir.

>No one would ever have imagined that the shogun would never come back. Not long after he left, the castle was surrendered, the palace closed down and the women thrown out into the cold. The girl whom Kazu gave to her husband was destined to be the last concubine of the shoguns.
