Aruna The thing with crossdressers Sarah is that they can basically shut down or block their femininity when they are not crossdressing. I too couldn't relate to many crossdressers except for the clothes, jewelry and make up part.
Even if not their looks many crossdressers are often comfortable with their body and genitals or the way people perceive them when it comes to their gender.
Crossdressing or the performance type of it which is often referred to as 'drag' is a form of art or hobby pursed by many males or sometimes secretly by some Trans women who are in denial or are confused due to our predominantly cis normative society or by Trans women who cannot be out to society or family at a particular stage in their life because of career, relationships, the place or region they live in etc. Crossdressing is not related to the person's sexual orientation or whether the person identifies as transgender or not. For me personally crossdressing doesn't help much. It doesn't matter what clothes I'm wearing be it in public or private, I'm still a woman.
