Tell your master that he should read something about BDSM basics. A D/s relationship is very personal and has to be tailored according to the needs and limits of each of the players... Therefore, any comparison between submissives is just plain stupid. It may also force one submissive to temper with his/her limits in order to win... which is suicidal for the relation itself.
