On crossdreaming or crossdressing as a fetish
"Fetishistic transvestism: The wearing of clothes of the opposite sex principally to obtain sexual excitement and to create the appearance of a person of the opposite sex. Fetishistic transvestism is distinguished from transsexual transvestism by its clear association with sexual arousal and the strong desire to remove the clothing once orgasm occurs and sexual arousal declines. It can occur as an earlier phase in the development of transsexualism." (F65.1)
This becomes even more paradoxical when it argues that fetishistic transvestitism can be an earlier phase of transsexualism: "Transsexualism: A desire to live and be accepted as a member of the opposite sex, usually accompanied by a sense of discomfort with, or inappropriateness of, one's anatomic sex, and a wish to have surgery and hormonal treatment to make one's body as congruent as possible with one's preferred sex."
"Freund’s term cross-gender fetishism came closer to describing this phenomenon than the familiar term transvestism, in that the definition of cross-gender fetishism explicitly included the element of cross-gender ideation. Freund’s concept of cross-gender fetishism still, however, implied the presence of a fetish-object, even if it allowed that object to be some symbol of femininity other than clothing."
Blanchard does not consider autogynephilia/crossdreaming a fetish, because for some autogynephiliacs there is no external object to get aroused by. There are no feminine garments that turn them on!
