What attracts you to submissive women? What made it click for you with your partner? What do you look for in a submissive?

There are certain phrases like good girl, that tone, a quirked eyebrow... that pretty much push a hot button with all submissives, but what are such triggers from your end?

(There has been some heated discussion between submissives, but) how do you (doms) define a doormat, who/how do you label it?
