I would hope that when anyone talks about demigods, they'd understand that the cultural context in play is, by definition, not monotheistic.
As for demigods, aren't most of them (in polytheistic mythology) born, often through an explicit sexual union? Whereas spirits/angels are either created through non-sexual acts, or spontaneously arise?
... Anyhow, when it comes to genies and sex, surely the definitive text on the matter, the TV show Weird Science, makes it clear that a genie such as Lisa can be as "fully functional" as she likes.![]()
In either version, the tv show or the movie, Lisa thought of Gary and Wyatt as her children, or at the very least her challenged nephews who need to be taught right from wrong, over and over again, although I think that Movie Lisa (naked in the shower with the lads) would have put out, but she was almost certainly playing chicken with two boys scared of their own shadows, and felt that her virtue was secure from everything, except their eyeballs.
