I love size disparity of all kinds. Tall, fat, muscular (preferably all of the above) guys towering over tiny, petite women. SSBBW amazons on top of average sized men. Large male feet compared to dainty female feet. A feminine little hand on a guy's meaty forearm. A tall busty girl standing next to her short and small chested friend. Weight gain progressions where you can compare the size difference of various body parts before and after. Big, bulky hands grabbing onto a thin waist. Anything that has a comparison with a large difference in size turns me on.
