Interesting story, Desirae (Post #53). Maybe there is something to your theory. I read posts on the forum that many CDers believe their crossdressing is genetic, because they say that from their earliest recollection they had these feelings. We don't have conscious recollections from birth, but in early infancy (say, up to two years old) there may have events that happened that stuck in our memory but remain unknown to us, and these events may run the range from fears to fetishes. My CDing is based on fetishes, not on some internal girl wanting to express herself. In the couple of million years that we can call us human, clothing is a relatively new invention, and articles of clothing commonly worn by women that have become objects of fetishes are even more recent. So it's absurd to think that a fetish for high heels, for example, is somewhere in the genes. Some say that the propensity to have a fetish may be genetic, and maybe so, but the actual object itself that is the fetish item must certainly have been introduced in childhood, perhaps before any conscious awareness of it.
So I think your theory may have validity, both for pleasure dressers and for those with internal feminine identities introduced in childhood, such as happened to you.
