How about some John Varley?

"Titanides come in two sexes, male and female. Both sexes have a rear vagina and uterus, and a large penis in the position where a horse's penis would be. Both sexes also possess humanoid breasts and can thus give birth to and suckle young.

Male Titanides have a frontal penis analogous to a human penis, and female Titanides have a frontal vagina. While sexual intercourse using the horse organs is indulged in casually between individuals of all sexes, so-called frontal intercourse is reserved for intimate relationships. The product of frontal intercourse is always a small, spherical egg a few centimetres in diameter. These eggs are often kept as keepsakes or mementos of special occasions. They are sterile unless first treated with the Wizard's saliva.

An egg which has been made fertile can be implanted in a rear vagina and "quickened" by rear intercourse. After that, the egg will develop into a young Titanide.

All Titanides can have eggs implanted. The Titanide who receives the egg is called the "hindmother". The Titanide who quickens the egg is called the "hindfather". The Titanides whose original act of intercourse produced the egg are the "foremother" and "forefather".

There is special case: a female Titanide may use semen from her ventral penis to produce an egg, transferring it by hand. If the egg is made fertile, she may then implant it in herself and quicken it with the same source of semen. The resulting offspring is a clone of the mother. Semen from the ventral penis can only produce an egg in the same individual who produces the semen. This is the so-called "Aeolian Solo" method of reproduction."
