She must be either petite or on the Average to small size and fit and thin. Because we are all very smart people here, it is unrealistic to assume anything as requirements in a relationship. There are too many personality variables. A master or Dom may think he is training his sub or slave. The truth is Dominant and Submissive train each other if you care about each other. I want a LTR and I am willing to be realistic and also have a romance and sweep her of her feet then take her into my dungeon.
