I don't know what cross-dressing is either, I just know I love wearing women's clothing. I don't have a conscious reason for it, that i know of, it is just a part of who I am. Wish you the best. It is one of those journeys that one starts and for most people there is not turning back. Dress at your own risk. Different folks approach it from different levels. The deeper you go the more fem it gets. Some find dressing a way of experimenting with their feminine side, others dive deep into all aspects of femininity.
