I agree with Nicole.

I guess it depends on how you define nature, if it is in the DNA, or if some event triggers a preference for feminine clothes in the brain, at an early or not so early age. Not saying that the CDing is or continues to be a fetish for everyone, but if we do just look at any other preference for unusual things, I don't think people are born with genes that regulate a preference for latex, or bondage, or feet, or any other strong preference that people can have.

I think that nature is only at the root when a person is transsexual or some form of intersex perhaps. There is a real need to look and live as a woman (for MtFs) in order to match internal gender identity, and it is accompanied by a strong distaste for looking and living as a male. If someone identifies as a male and does not hate their penis but just has an intense attraction to the clothes or to wanting to look like a beautiful woman, then I think this is mostly nurture - an internal need brought on by some type of accidental imprinting, and not necessarily a need brought on by something external if for example their mothers or their sisters dressed them as children ... although this is possible too. But then again maybe some people have personalities that are more susceptible to the influence of one-time accidental events, or events that occurred several times. If the personality causes a person to be easily influenced by things or events, then I supposed this would be nature, although not necessarily for the CDing. If this makes sense.

To the CDers who always felt different than other boys, unless you are TS and don't know it yet, I know some men who are not CDers, are not gay, but who don't have the same interests as other men. One such friend is an historian. He is the least macho man that I've ever met! It happens without necessarily predicting a preference for the CDing, just as there are women who are very sports-minded and competitive and who hated all the ultra girly stuff during childhood ... and they still have a solid preference for presenting as a female.

As always, this is just an opinion.
