I was there yesterday just looking to get warm on such a fucking cold day, but I accidentally struck gold.
Here's the deal. A guy told me that M-F it's basically a standard Korean spa. There's a men's area and a women's area, and massage and acupressure services. In each of the two areas is steam, sauna, showers, and a lounge. In the shared area there are two dry saunas (and both are GREAT). On Sunday (and maybe Saturday?) the entire place becomes male. No women are allowed. So now guys have the run of the entire place.
It's a full-blown bathhouse. Even in bathhouses I've been, I've never seen more in-your-face public sex: stroking and sucking only. No one was doing anything anal. But guys were passing poppers around, sucking dick with an audience, circle jerking... The works. Because it's not an actual bathhouse, there are no private rooms. That means that everything happens right in the open. For guys who are exhibitionistic or voyeuristic, this place is a dream come true.
The crowd leans young. Most guys are Black, Latin, or Asian, in that order, and there was a handful of White guys. I saw all kinds of bodies, and there didn't seem to be any body shaming or cruelty. I've been in places where the hot guys only play with or in the site of other hot guys. Maybe because in this place all the sex is right out in the open, you can't be exclusionary. Lot's of great IRL porn scenes for everyone to watch.
No way to prove this, but I'd guess that a lot of the guys are DL. Because this joint bills itself as a legit male-female spa, a DL guy can go there and not give anything away. There's no way to tell for sure, but that was the vibe I picked up.
And it's only $15 entrance. Can't beat it.
