And I err favouring some sort of historical correctness over gender neutrality - there has so far been no female warriors for instance, and most authority figures have been male.
I'll introduce some more important women, now that I think of it.
My campaign is somewhat of a compromise -- baseline is patriarchial, with male primogeniture assumed for example as part of the faux Western European medieval-ish setting, but there are plenty of female warriors, etc.
Sex is basically a non-issue when I DM. Relations (with or without PCs involved in them) are there, but I'm not in to describing sexual scenes
Similar for me, but there have been some PG-13 scenes. One of the male players does like to hit on female NPCs pretty often, but usually either nothing happens 'cause they're not interested (ah, realism!) or we jump cut to after wards and I let people assume what happened.
Sexual violence (between NPCs) is something I have used before, and would do again, for much the same reason it's common in detective stories - it makes people angry and involved.
I don't, because it doesn't fit the PG-13 ethos of not offending anybody too much. I know one of my (male) players has issues with this sort of theme, so fair enough to just not have it, ever.
For other groups I don't know as well, seems safest to skip it.
