Some erotic art, notably that of Japan, is characterised by immense exaggeration of the sexual organs. The penis and vulva are often drawn three or four times their proper size: the penis, for example, can resemble a forearm, and the female organ often "assumes the length and width of the folded sleeve opening of a kimono".

One extraordinary feature of Japanese erotic art is the depiction of the penis as a duelling weapon. Drawings show two men, both equipped with mighty organs, fencing with the erect members. There are also other forms of penis competitions: men are depicted going along to have vast organs measured to see who possesses the largest.

In one drawing a man equipped with a penis about the size of all the rest of him is obliged to support the mighty organ on a pair of wagon wheels trundling before him! A sexual hero of China was said to be able to smash a copper pot with one blow of his penis!
