Transvestic fetishism is typically defined as a fetish in which there is a sexual or erotic interest in cross-dressing or dressing in clothing items distinctly associated with the opposite sex. This fetish is most often seen in heterosexual men.
Transvestic fetishism has historically been described as a "paraphilia" or sexual disorder. Currently, there is serious debate about the degree to which fetishes like transvestism should be considered "disorders" as opposed to merely variations in the vast landscape of sexual tastes and proclivities.
