He should be offered 5 minutes to waltz into the girl’s locker room, shower, and get dressed. THEN the girls can make use the facilities. Anything else is about getting to expose himself and to get an eyeful of voyeurism.
He’s got the room if he needs it. His goals are something else.
I had to deal with a man who thought he was a woman at work.
He needed everyone to validate the delusion to be happy. Announced as woman, immediately at the women’s luncheons, women employee groups, in the bathroom, etc. It wasn’t enough to wear the dress, makeup, hair. It attended events, as soon as it could, asked for a welcome and gushed how great it was to be there, then took over fawning and seeking attention.
It couldn’t be happy walking into the women’s room but tried to chat up women who were there, discussing “female” topics.
It was like someone who thinks they are Napoleon unable to be happy dressed as Napoleon in the corner, but must have everyone else calling them the title to truly be happy.
