I think we can probably all agree that crossdressers share the desire/need/compulsion to wear clothing normally associated with the opposite sex. But that is as far as it goes in my opinion. We are not all first-born, left-handed, artistic, liberal, etc, etc.
We dress for different reasons, we started at different ages, we like different styles, we have different approaches toward society. OMG, we are just like everyone else, different!
