There is no huge demand, you're a minority amongst a minority.
That said, there is some, it's just mostly porn games, most of which are incomplete.
If I had to recommend something, I'd go with either Strive Conquest or Ravager. Both have something going for them besides just porn (Strive has some actual gameplay with turn-based fights and slave management, Ravager has an actual story and setting), and in both you can pork women of different species, although in Ravager it's only true because you play as dragon.
Those two, while not 1.0, at least release meaningful-ish updates once in a while so they are actually likely to be finished at some point. There is also stuff like Lilith's Throne, but that one is a never ever EVER, despite how good the sex system is.
