Appreciate it ✌The Submissive stats on each LI page shows how Submissive they are, the Dominance stat shows how Dominant they are. There won't be any femdom before you ask, or maledom... the submissive stats is purely there to show how much persuasion or influence you can have over a LI, in the way of say Rita making her not take a morning after pill, or say Libby being a little more adventurous with the MC if higher.
With regards to the Dominance stats that will mainly be for different dialogues if they are more dominant that not.
