Honestly, this is supposed the be a "light, fun, sexy" game.  There are dozens of games for hardcore/BDSM/kink-filled stuff.  If the characters don't fit the "light, fun, sexy" theme, and help enhance the experience for everyone, then they don't really belong.  I'm all for including everyone and having fun, but there's a fine line between including everyone and alienating those of us who signed up for the game as it was advertised.
