There's a lot that goes into "being the girl" on a date. A lot of it has to do with attitude and presentation, not necessarily with etiquette. For example, in a recent thread about "passing" someone mentioned posture and gait. That's a big part of it. There's plenty of space between walking around like a dude in a dress and prancing around giddily like our friend Phox on Youtube. Embrace it! When you are on a date with a guy, theres a 98% chance that the guy is totally turned on by the fact that you are a CD and not a ciswoman. It's clear to them and to the world that you/we are not trying to fool anyone. We are simply ourselves.
That said, he doesn't want to be reminded by our presentation that we are, essentially, a man in a dress. That includes anything from posture to attitude to hairy arms and hands. So you present and carry yourself in a way that is subtle yet confident. There's no shame in this game! Many guys I have dated say that they love how much care I put into looking feminine and attractive.
There are small cues in the way that we walk - again, posture and gait - and the way that we occupy space. A simple example: When a guy gets into the passenger seat of a car, he usually swings his left leg into the footwell, sits down, and then brings his right leg in. When a woman gets into the passenger seat of a car, she usually will back her rear end into the seat bottom while facing the open door, then pivot towards the windshield while bring both legs in together. Such a subtle thing makes all the difference in the world. It sends a message about who we are and what our relationship is to the space that we occupy.
That's just one example.
