transvestism

noun

1. (uncountable, usually)The condition of being a transvestite.

   “Transexualism. Where the compulsive urge reaches beyond female vestments, and becomes an urge for gender ("sex") change, transvestism becomes "transexualism." The term is misleading; actually, "transgenderism" is meant, because sexuality is not a major factor in primary transvestism. Psychologically, the transexual often differs from the simple cross-dresser; he is conscious at all times of a strong desire to be a woman, and the urge can be truly consuming.”

2. (uncountable, usually)A paraphilia typically found in heterosexual males characterized by compulsively seeking and deriving sexual arousal from cross-dressing, especially if the urges and behavior cause the patient distress or social impairment.
3. (dated, uncountable, usually)sexual mimicry
