Oh for crying out loud, I think this is just your uncomfortableness at being naked. Think of children - they love running around naked! They dont care and they love getting naked together. Sure, this of course gets disciplined as we get older but at the end of the day its a maturity thing in my opinion. I live in Japan for a month when I was 16, maybe I just loved the culture and how respectful they were but I enjoyed going to an onshen (womens bath house). Its a little weird at first, but you get over it. People who are pedantic about getting changed in public in my opinion are just worried about people maybe laughing at them? Well thats their immaturity that they have to deal with. As a young woman, theres nothing on my body that another woman has not already seen, so at the end of the day - who cares?
