Captain, if you pass as a guy use the men's, I do all the time. My first time was on campus going to lecture in a building that I don't normal go into; I was walking alone and needed to go so asked the security person standing there and she pointed across the hallway. as a got so I could see the door I realized it said men's, needing to go and didn't have much time decided to go in. I saw the urinals first then the stalls in back so walked to the stalls, went in one, said I am here so just sit and pee and that is what I did. I opened the door and there were 6-8 guys doing there thing, so I washed and dried my hands and walked out and went to class. Only after I sat down in the lecture hall did it really dawn on me what I had done. That was almost 2 yrs ago, now I use the men's in a building on campus near where I have most of my class. Many of the students in the building where I have most of my classes know my history so I don't want to use either restroom there where they could see. I am seen now as one of the guys by most of my fellow students and the professors too.
