God does not have sex with anyone.
Pagans believed that their gods were far too high to become man. Many thought the gods did not care about human affairs.
“[T]here is no evidence that the portrayal of Jesus in the Synoptic Gospels (the three earliest gospels of Mark, Matthew, and Luke) was directly influenced by pagan mythology in any significant way. Rather, it is widely agreed that the portrayal of Jesus in the gospels is deeply influenced by Jewish tradition.The earliest followers of Jesus were devout Jews who abhorred Paganism, and would have been unlikely to shape their accounts of their founder on pagan myths…most of the alleged parallels between Jesus and pagan deities only exist in the modern imagination, and there are no "accounts of others who were born to virgin mothers and who died as an atonement for sin and then were raised from the dead". The attitudes towards resurrection were generally negative among pagans.For example, Asclepius was killed by Zeus for using herbs to resurrect the dead, but by his father Apollo's request, was subsequently immortalized as a star.”
“According to historian of religion Jonathan Z. Smith, modern scholars hold that "dying and rising gods" trope is incorrect since early sources on numerous gods show that gods who have died, do not resurrect or even go through rebirth. Furthermore, claims of dying and resurrected gods is based on dubious reconstructions of later sources since early indigenous sources never make such claims, and there is no clear instance of a dying and rising deity.”
