Do male only spaces still exist? Do men even want them anymore? Even the ones that seem to form naturally seem to throw everything out the window to accommodate a woman who wants in. Even threads I've been in will be going great, lots of natural discussion, then a woman walks in asking 'are girls allowed here?' and suddenly the whole thread is about a girl, one without even a photo, getting all of the guys to talk to her for the rest of the night.

As much as we give women grief for invading mens spaces, men tend to welcome them in, if not invite them themselves.

What kind of mens only spaces would you enjoy or like to see? What kind of real world mens space would you appreciate enough to be a monthly or regular customer of?
