Why can't the option be there for the main character to grow to accept and embrace their life on (and in) the bottom without it devolving into a shame spiral?
The shame play is part of the fetish I guess, and if you think about it, no matter what you do in the game you will end up losing dignity because, bottom or top, you are fucking unwashed goblins, werebitches, brigands and harpies that probably can't wipe their own butts because they have no hands. Dignity is out the window on most encounters
The only way to keep your dignity is to not fuck anyone, maybe the companions get a pass, but there is an achievement if you remain a virgin throughout the game.
Sure, it seems to be a bit tasteless to make dignity and femininity go together, but it is not meant to be taken seriously, it is just a dumb fetish.
