The Congress of the Cow mimics a Bull mounting a cow, hence the name. The woman leans forward, supporting herself on her hands and feet, and offers her genitals for a rear entry position.  

The man is able to penetrate his partner very deeply from this position. It is highly symbolic of animal mating rituals and can therefore become very hot and thrusting as it brings out the primitive in us. 

The sensation on the male urgently pounding against one’s buttocks is highly arousing. If further stimulation is required for the woman to reach orgasm, the Clitoris is a short reach around the front of her thighs.

Rear entry positions are highly erotic and very popular in situations when good old-fashioned, non-PC cave-man sex is required as there is no eye contact, just the call of the wild.
