First, there is sexy content. But since it's a slow burn, it will be a sexy massage or teasing. I let you discover that.
The allignment system doesn't change any H-content. Holy, Scarlet and Undeath (Not corruption ^^) will change some dialogue (only one so far).
The only real change is Whitemane route : Dominant or dominated ? If you want more a sexy content, go for dominated. If it's not your kink, dominant still has a few things and in due time, any H content will be available with both route.
Glad you enjoy my game !
