Because I love and am attracted to the look of a very curvy, sexy, pretty young woman. So much that I want to be that woman, the closest I can come is with her(female) clothing and makeup. I love the cut and soft fabrics of womens clothing and underwear. I like to look in the mirrow as I dress and see how sexy, curvy and femine I am becoming and I love to walk in heels, straight skirt, the jiggle and weight of my D breast forms. I could go on forever, being a good looking, well built man just doesn't even compare or come close.
