Hey, the PH isn't /that/ bad.
I suspect that one would run afoul of RL concerns more precipitously and dramatically than the presentation of religion has. (Good luck presenting it as gender-neutral, too.)
Supernatural, OTOH, NP, there's the charmed condition, spells that impose it, etc...
Magical beauty is a D&D archetype. We see it explicitly in Dryad, Succubus, and other creatures. It is part of the flavor of the Elf, albeit absent from the mechanics, albeit again, it surfaces in the mechanics of the Charismatic Drow and the Charismatic Eladrin.
It is an important archetype.
It is obviously easy to make it gender-neutral, emphasizing appealing examples of masculinity, femininity, and androgyny.
And when male seducer seduces male ... well, its magic. Compare the Girdle of Opposite Gender.
The gaming design can make this archetype work.
Heh, at the very least, it will help alleviate the heterosupremacist archetypes.
Edit: I feel the mechanics of charm, suggestion, and domination can (must) stop short of actual sex. But the flirtation can be fun for the story.
Also, magical beauty helps clarify the meaning of Charisma. In some old school traditions, physical beauty corresponded to the Charisma score. However, Charisma is a mental ability, not a physical ability. The 1e UA attempted to emphasize the difference.
Here however, Charisma is artistic appeal − and in this case − the innate magical force of Charisma projects as supernatural beauty − impossibly beautiful.
