You wouldn't be asking the question if you were comfortable with it and any time you're not comfortable with something you shouldn't be pressured into doing it.
No big deal. Most of us were required to dress and shower together for P.E. In school.
You better get use to it. Sports p.e. Prison jail hospitals their is naked bodies everywhere
Some people are uncomfortable with nudity. No me though.
Sometimes it depends how you're raised if nudity is uncomfortable to some or not . To answer your question , yes, it's okay to do that- but if you or anyone else feels uncomfortable , change somewhere else .
From the looks of your other questions I would say you might have some issues with nudity.
If you don't have a problem with it ... Why have your last 2 questions been about similar things?
Millions of people change in front of others ... It's pretty much required in jr/high school, in America (before/after PE class).
