This essay is not particularly well written, but contains enough semi-sordid educational material that it is worth reading.
For example, the founding myth of Japan has the first two deities as a husband and wife:
A charming account of their courtship follows, in which the god and goddess shyly discover each other's sexual parts and Izanagi declares:
"I wish to unite this source-place of my body to the source-place of thy body.''Their first offspring were islands; then came a profusion of gods and goddesses, one of whom was Amaterasu, the sun goddess.
I wonder if that "source-place of my body" line works in bars in Japan today.
