I reckon as others surely already have noted (no I am not calling you Shirley), the movie feels like it is a spiritual successor to Fire and Ice. So if you liked that adult piece of animation, you surely will dig this one too. A lot of violence, blood and gore make this fantastical journey quite the interesting experience.
There is also quite a lot of nudity. Yes everything is drawn, so I am not sure how much all that makes you feel (uncomfortable, nauseous or plain sick). If you can suspend your disbelief - and do not have issues with animated movies for grown ups - well I think you can figure out the rest. Also you should be into fantasy, which I think I covered with the Fire and Ice reference - although you may not know what that is. And you do not have to watch that to see this. Although if you are thinking of watching it, maybe it would make sense to watch that before you watch this one. Just technologically speaking - not story wise. Anyway, go ahead give it a shot ... or any other sliced body part you feel comfortable with.
