Same here, on both counts.
Again, same here.
I never thought about the use of fake names as reminding one of being in the closet, but that's a great point. For me, it was too much to remember and keep track of. When I used a fake name and would then not respond when the guy would use "my" name it was obvious it was fake.
I used to hire a guy who would host me at his apartment from time to time. At first, if he escorted me upstairs we did not have to go through the rigamaroll of presenting and swiping an ID. Then the policy changes and guests whom he met in the lobby and escorted up had to present their ID and it became too much trouble for him to host. We would simply play at my hotel.
