I tend to particularly enjoy: Kemonomimi/animal characteristics BDSM/S&M Smut (particularly lewdness)
I will sacrifice my morals if a story has something good enough to offer (like has rape but also has really good smut or redemption arc.) But I will mention if there are questionable things in a manga so you know beforehand.
I absolutely will not read: Shota Excessive abuse/gore (or at the very least highly likely won't be a favorite) Beastiality
