It certainly seems that most of us (probably a significant majority) are pretty down on our male selves, and “pretty down” is probably a serious understatement.
Although it’s important to not lose sight of the possible (and very likely) genetic component, I think this school of thought has some merit. There is a school of thought that views cross-dressing as a way for inadequate males-who aren’t really inadequate, I must stress, they only feel that way which is bad enough, of course-to gain a sense of self-worth, by emulating in themselves the traits that they view to be most desirable in another person: to wit, a sweetly feminine face, gorgeous long hair (for me, at least), a killer figure rocking a little black dress, and so on.
