This is very true, thank you for reinforcing this.
A transsexual feels a complete disconnect with her birth sex, AND her assigned gender role and expression.
Unlike transsexuals, crossdressers DO NOT FEEL ANY disconnect with their birth sex (except maybe the crossdressers who toy with the idea of breast creams), although they do experience some disconnect (to varying degrees) with their assigned gender expression (and perhaps gender roles, for the crossdressers who fantasize about being maids, sissies, etc). This is why they dress. If there was no disconnect with socially assigned gender expression, they wouldn't dress with forms, wigs, and makeup, would they?
