Though it likely doesn't interest you, the idea of a "divine phallus" is ubiquitous so far as ancient religions and their symbolism are concerned:
Throughout the ancient Mediterranean, Middle East and even into India, images of Priapus (or Hermes, or some other phallic deity) with a phallus were used in deflowering rituals of newlywed virgin brides. Though the bride would later consummate the marriage with her husband, the deity was said to impregnate her with her firstborn child.
Wikipedia, Priapus.
In the ancient religious symbolism, the firstborn child of every virgin was conceived through the
jus primae noctis of the tribal deity. Ritually speaking, the virgin bride would enter the temple where there was a wooden or metal phallus representing the tribal god and she'd deflower herself symbolizing that her firstborn was the tribal god's son. This firstborn would then be a priest serving in the temple where he was ritually conceived. Even in Judaism there's the ritual of
pidyon haben where the parents "redeem" the firstborn male from temple servitude by purchasing him from that responsibility.
As in all myths of divine births, the maiden might have an earthly husband, but he didn't lie with her until after she brought forth her firstborn child, who was the son of God . . ..
Barbara G. Walker, TWEMS, p. 311.
She didn't lie with her bridegroom until she deflowered herself on the divine organ of the tribal god.
Even the form itself, under which the god was represented, appear to them a mockery of all piety and devotion, and more fit to be placed in a brothel than a temple. But the forms and ceremonies of a religion are not always to be understood in their direct and obvious sense; but are to be considered as symbolical representations of some hidden meaning, which may be extremely wise and just, though the symbols themselves, to those who know not their true signification, may appear in the highest degree absurd and extravagant.
