Have y'all ever had to get changed in the same room as the girls in school? If so until what age?

Like getting changed for sports/PE etc. What age or school year did you finally, go in seperate rooms?

My primary school made us get changed in the same room until year 5 (grade 6 i think for americans) and even in year 4, as 9 year olds we had to get changed in the same room!! And it was always soo embarrasing..

Please share your storys! I'm really curious about everyone else's schools and experiences with this.

Edit: Doesn't have to be school, it could be other places.
