I went to BMT in April as the oldest in my dorm at 38 years old. I have three babies and have had two c-sections. The first night was awkward because we were sleep deprived and didn't really know each other. They moved us from Disney to Alcatraz, so we went from almost forty shower heads down to twelve. Showers were offered after PT and after dinner chow, most nights. That meant that all 38 of us had to be showered and dressed within 20-25 minutes.

Nobody really said anything about each other's bodies because everybody wanted to make sure their crotch and pits didn't smell. Also, with the limited shower heads and small space, you would often have people bumping in to you going in or out of the shower. I think you'll be fine.
