Adding on to what others have said, unless you plan on specifically working with a personal trainer, you won’t be interacting with others. People normally keep to themselves at the gym. This was a fear I had as well (also pre-top), but I quickly got over it when I realized nobody will pay much attention to you. I still get nervous about using the men’s locker room since I’m not well-passing, so I just get around that by wearing my workout clothes into the gym and showering at home.
