Son is receiving mixed gender swimming lessons with a mixed gender communal changing area. Am I wrong in thinking that this should be changed?

My son is 9, in Year 4 (UK, 8-9 year olds) and has started receiving swimming lessons provided by the school along with the rest of his year. Swimming lessons being mixed gender is something new to me as boys and girls had seperate lessons when I was younger. That isn't really a big deal, times change and I guess it's a thing now now to have swimming lessons together.The problem I have is there's only one changing area and it's communal with no cubicles, so the boys and girls have to undress completely nude around each other. I was quite shocked when I learnt this, they're in the same area with nothing seperating them, boys are on one side, girls on the other. I asked my son if he's comfortable with this and he said he hates it, he says he doesnt like being naked around girls, it's awkward seeing them nude, and they're even more embarrassed than he is, trying their best to change into their swimsuits while covering with towels. He says the boys and girls are always laughing if they see each other naked, and one of the boys was intentionally undressing next the girls to gross them out. Apparently one girl was was crying after refusing to get changed. Some boys and girls are even going to school now with their swimwear already on underneath their clothes.I contacted the headteacher about this and the response I got was that they're trying to do away with gender segregation, they're saving time and money, and changing around each other is no big deal at that age because they do it anyway during PE. Apparently stripping nude is the same as changing into PE kit to her. I feel like this push by the school to be more progressive is doing more harm than good and could cause long lasting self confidence and body image issues, I would be mortified if I had to change into my swimsuit around boys at that age.Talking with parents, i'm receiving a mixed responses with some being for it, some against, and some not being bothered. This also surprised me because I thought the overwhelming response would be people on my side. This is what prompted me to post this here. Am I in the wrong here? Am I just out of touch and worrying too much? I know that progressivism and making things mixed gender is the big thing now, but I feel like it's been taken too far here. via /r/Parenting http://ift.tt/2xlvkhr
