I have a similar experience with shared showers for sports teams being trans. I never participated and my teammates thought I was weird because of that. I didn’t know I was trans but I did know I felt highly uncomfortable in my body and didn’t want anyone else to see it.

Still I think that there is a way to create a healthy culture around nude activities, but we should probably focus first on destroying capitalism and liberalism before trying to find out if reforming culture towards being more accepting of nudity is a good thing. Currently such culture will sadly be used to exploit women and children and oppress people who don’t fit in society norms.
