Naw, none of those. I'm writing at a niche due to the amount of categories it falls under, rather than something like that. 'ere we go, brace yourself. Apologise if this is TMI.
First off its got anthro characters, so thats quite a large split already. Futa's, which are hit or miss. Sci-fi/aliens which seems to be less popular than fantasy from my observations. The main sex scenes i'm refering to are typically Futa on male with size difference/domination aspects. Speaking specificially about the Futa side of it, I think F/M is the least popular of the possible combinations. There is some non-con/rape stuff (Although the rewrite hasn't hit any of these yet) but I tread quite lightly there.
Long story short, huge futa alien on male with some non-con sometimes. Eithers thats gonna gross you out or more likely, its "eh, not my thing" for any number of reasons. I know the people that like that stuff have enjoyed the written work but that circles back to my initial question.
