In my opinion a good submissive is one who finds that they want to please another with their service, their actions.
also just my opinion...there is no such thing as ..too old, too fat, not submissive enough...etc.
Ok so you arent a "runway model" not many people are...and if your dom cant see the beauty that you are ...then he misses out. There are plenty of people in the world who will love you for who you are ...and not your measurements. There is more to you then just how much you weigh or how big your breasts are. Please believe that.
