Gentlemen clubs, country clubs, bars (although I don't think it should have been single gender), other than this.. I can't name many of the other ones. They were mostly gone by the time I became an adult.

Anyways, I have heard of discrimination that men have faced when trying to create "safe"/support groups that were men only.

I don't think I understand the desire or the concern here. Look around the BBQ in the back yard at any party anywhere in 'merica and you'll find the guys hanging out and chatting away from their wives. Look at sports teams in your high schools, colleges, and local clubs and you'll find men hanging out together. Look at Men's bible study groups or similar if that's your thing. Go to the local men's barber shop and find a bunch of guys getting haircuts. Invite your buddies to your place to watch the game...

I don't know about your experience. But my experience: BBQs are typically a party situation with your household and others. If it's just the guys that's a friends thing.

I haven't heard of such of a clubs.

I'll agree with you on this. That qualifies for what I was suggesting. It's a social thing and gets people to talk.

Is that an environment that guys would open up? Most of these places tend to be "mind your own business and lets not talk that much" kinds of places.

The Freemasons are still here, and though numerically shrinking as postwar members pass on, we're experiencing a renaissance as a new generation of men come through with a greater interest in the spiritual and philosophical aspects of the craft.

Would recommend it wholeheartedly.

The workplace used to be a male space.

There were all-male colleges and many all-male secondary schools (mostly private) in the US till the 1960s.

It's worth noting that many institutions you would not have thought of as "men's colleges" per se were indeed all male -- Caltech didn't admit women as undergrads until 1970.

"Male", not "men", but Boy Scouts.
