Yes. If you weren't aware, the YMCA was a very common meeting/cruising place for gay men back in the day. The YMCA used to be known for providing cheap food and housing, so it attracted a lot of dudes to come stay there and some of them were gay. Gay bars weren't really a thing for the most part, so other places like the YMCA became the default. It's even more convenient if you already happen to live there.

As early as 1919, the YMCA was already a common cruising spot for both members of the US military and civilians. Some guy went up to FDR (Assistant Secretary of the Navy at the time) and was like "Want me to catch some of the gay dudes in the Navy?" When FDR approved, the Navy sent undercover twinks to the YMCA in Newport, Rhode Island to fuck a bunch dudes and report back like, "Yep, they were gay. I know because we fucked." Pretty shitty, since the result was a court-martial and some people ended up getting sent to naval prison or dishonorably discharged (a few were found not guilty). The investigators rarely expressed any objection to the sexual acts in their reports, either, so it's a little messed up that they'd get dudes in trouble for fucking by fucking them. I can still find an element of humor, though, in the fact that the US Navy was cool with sending specifically young, good-looking dudes to honeypot sailors into boning as a means of investigation all the way back in 1919. It was known as the Newport sex scandal if you want to read more.
