Gym /. Swimming changing issue

[BelfastDadof3]

I'll start first and say I'm sorry for intruding on a safe space for women.
Am a single dad (widow but not recent) with three kids 2 girls 11 +13 and a 9yr old boy.

Also I'd say kids are bright and confident, very excepting as I've tried to bring them up to accept all body shapes and not point / shame.

I go to the gym three times a week, do my workout and the kids have a supervised kids swim lesson (just the three of them) and I meet them after for a swim and play.

There isn't family changing, but I don't think it's applicable as my girls are old enough.

So having a muffin after the swim my 9yr old boy asked me.
"dad, why do most of the men walk about naked in the changing room?Willie's out. Is it not normal to have a towel around you untill you get your pants on."

So I said some people were just very free, but I think it's a bit over the top. Bit of a discussion about respecting others space etc and then my boy said" it's also odd that some shave all their body hair off, even the old fat men, it's weird looking"

Normal ish conversation.

Then he asked the girls what happens in the changing rooms. They were a bit horrified and said that most women and girls had big towels and kept private. Because - their words " girls arnt horrible like boys"

Then the eldest daughter said "a room full of men drying their bits would be duscusting. When the [transwoman - edited by MNHQ] is in the changing room we use the disabled cubicle. There's lots of room and we don't have to see him dry his bits. And (jokingly) his man bum and huge boobs do not look nice."

So really I don't know how to approach this.
I presumed that if a man transfered to a trans woman he would have female genitals. Maybe I'm niave.

It's a really nice gym and pool - Bannatynes - a treat for the kids..
Is this the same everywhere?
If I raise it with the manager am I being transphobic to suggest no penises in the female changing?

I've only just stumbled across this thread. Made me feel sick. If that happened to my daughters I'd be waiting for him to come back and I'd deal with him myself.

My DD is a member of a swimming club that uses a council owned pool. The pool has unisex changing rooms. When the club is in no one else swims but the kids have to use groupchange (separated boys and girls) in case a member of the public comes in as technically other areas are open to the public - although really they should be using dry change areas.

Last week a random man chose to walk around the unisex area butt naked. No one knows who or why he was there. Luckily the kids reported it and my DD didn't see anything but I'm still inwardly seething a week later. All I can say is that man is lucky that a group of swim Dads in Dudley didn't find him first.
Sick of these exhibitionists and their apologists.

Husbands used to do this to get the right to rape their wives.
Some men just can't see it as demanding to be an abuser. It's always "just" a question of rights.
