There are places where women feel comfortable simply because they are women, and places where men feel comfortable simply because they are men. For example, where I live, coffee houses are only for men. There's a lot of noise and swearing. If women were there, people would probably pay attention to the noise, swearing, and certain behaviors.
It's the same with Turkish baths. There are baths exclusively for women. On the other hand, there are baths that only men are allowed to enter. A married woman might not want to be in the same place as another married man. We should understand and accept the existence of such places; they are necessary.
I think the conversation about these kinds of places is silly. It is like me demanding to go to a hen's night for friends I don't even know.
