it wouldn't enter the head of the purest, kindest man in the universe to access a female only changing room or toilet, why would it? They know damn well their presence would at the bare minimum cause discomfort to the women in there and they would never dream of doing that which leaves one to wonder at the mindset of those who do want to do that and are perfectly at ease with disregarding any feelings but their own.
My son is 17 and wears dresses, skirts...anything 'typically' seen as women's wear. He is nine stone soaking wet and with his long hair he often gets mistaken, for only a second, as a young woman. My husband and I have been very diligent with him - any hint from people that they think he is trans gets shot down immediately by us or, if it is said to him without us being present, was talked through at great length with him. He is also autistic. He knows and likes that he is a GNC male, despite all the sickening and rude comments he has faced in his life!! My husband and I take some credit for that.
Anyway to cut a long story short, he would NEVER enter women's spaces. He wouldn't dream of it. He is the man who crosses the damn street so he isn't walking behind women. His respect for women is part of him. If he has it they can all have it, but they don't.
