Think "bath house." Especially back in the late 70's and early 80's before people finally started screaming loudly enough to drown out the fags' "oppression" whining and shut the damned things down as a menace to public health.
They were (semi-)public baths you could enter (for a pretty small fee) where no end of debauchery took place. "Bath house" was synonymous with "place wot lets gay men fuck each other uninterrupted." They absolutely could pair off with a half-dozen fellow perverts on any given visit if they had a few hours to spend.
It's hard to overstate just how much fucking the gay community engages in. They're not all like this but a very large portion of gay men are astonishingly promiscuous. AIDS was originally called GRIDS ("Gay-Related Immuno-Deficiency Syndrome") and "the gay plague" because of its plainly obvious connection to rampant unprotected butt sex. Even seeing acquaintances dropping like flies couldn't stop the orgy, and that's how AIDS was eventually introduced into the general population (some closet queer went home and pozzed his beard, and it went from there).
Semi-related: 'member the monkeypox outbreak a couple years ago? An update to the existing vaccine for it successfully nipped it in the bud, but it remained controversial among the fags because it required 30 days to become effective and it was common advice not to have sex during that period with someone known or suspected to be a carrier. This outraged them so much because god forbid someone ask them to keep it in their pants for a month. And as always, most of them chose to risk contracting a life-threatening disease (or passing it on) because they just couldn't help themselves.
