I personally started using the men's room when I started getting confused and frightened looks in the women's room, even though I was petrified to start going into the men's room.
Empecé a usar el baño de hombres, cuando empecé a recibir miradas confundidas y espantadas en el baño de mujeres, a pesar de que me aterraba comenzar a entrar en el baño de hombres.
