THE CUCKOLD PHENOMENON 2 :In art.-nsfw-subject to edit.

I am interested in the culture and history surrounding cuckold ism, both as an investigation in to the psycho sexual reasons behind it, and how this is represented in art. Most fetishes have an active art scene, which is viewed separately from the photographic representations of the sexual act. So what is going on?. The art must serve as another purpose. 

Isaac Cruickshank-circa 1800 'The cuckold departs for the hunt'.

In which we can see the ironic title, with a man under the bed, who is making the 'cuckold' gesture at the departing husband. This is a moral etching, not the pornography of later years.

Here we can see the man holding the baby, he is making the symbolic horns gesture, suggesting the paternity of the child is up for question. The man grinning, in the background suggests he is the real father. Pots and pitchers and ladles dipping in to them were sexual metaphors.Vemeer used them a lot.

Horns representing the cuckold. The male fear of raising another persons child and not passing on ones genetic material is an old fear in art. (researching artist)

And the modern version of the cuckold, latent homosexuality, the man tied up, impotent, but with an erection. He is a 'sissy' a man humiliated by the 'bull' who is having sex with his wife. The modern pornographic phenomenon of cuckoldism is very different from it's origins. Now the male is a willing passive participant. I have seen cuckold art that represents homosexual contact between the bull and the sissy, but mainly it is the white guy watching his wife having sex with a larger black man while he is humiliated, gaining sexual satisfaction from being dominated .

Pertinent to the subject is this amusing and educating website which details the porn habits of other countries.The website is very safe, and contains no nudity rather a graph that is highlighted as one drags the curser over the relevant country.
