Transvestism

She made two movies on the cultural history of transvestism.

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.
