That's... a good question. If you mean itch.io tags, nsfw (which I've now added, because I'm an idiot), maaaaybe monster girls (Do Fae Folk count as monster girls?), maybe LGBT depending on how I feel (there are characters I plan on being bi or lesbians, but I don't know if they count in this case or if it will necessarily come up when I write the scenes involving them. I don't want to have two background women kiss and go "Look! Lesbians! I can say it has LGBT now!"). Itch.io has a lot of tags and they're not exactly the easiest to see definitions for.
As far as standard sexual "tags" go... well, okay, I may have to see what itch.io rules say I can post in comments before I start typing those.
