In the matter of locker room etiquette. I legit do not care if women are in the men's changing room. I do not care if a woman sees me naked. We offer a women's only space to protect a woman from those who have penis. Not really the other way around.

Do any guys really care if a woman sees you changing?

We should just change it two one changing room for anyone. And another changing room where Penises and balls are strictly forbidden.

If someone is retarded enough to cut their own dick off wear makeup to go into the no penis room fine.

They aren't women. But they aren't real men either.
