I've been there a couple of times with my boyfriend during men-only hours, and a few times with straight friends during coed. I've gotta say I really love it. Bodies of all shapes and sizes, and I honestly didn't feel that there was any sniffiness or prejudice about kinds of bodies. There's a long central corridor where guys just sit and hang (partially because they need a break; that heat is serious; bring a water bottle for sure), and it's definitely cruisey-flirty. Lots of strategic towel-adjusting, or just plain nudity. As others have said, the steam room is where most of the action happens, because it's just so hard to see. The attendant that I've seen both times during men-only hours is firm but fair, like a hot Mary Poppins. I chatted with him last time, and said to him how much I appreciated his gentle rebukes. Honestly, if he weren't there I think it would just turn into an orgy. For me at least, it's more fun because it's surreptitious.
Because this is LPSG, I'll dish a little. The first room we went into (Turkish), there was a furry-backed bearded bear, wedding ring, with a true tube steak hanging between his legs. Towel fully open, but very studiedly neutral and no eye-contact. Later in the afternoon, we went into the Redwood room, and he was in there having it stroked by another guy, and pawing at his chest. Eventually we circled back, and my boyfriend, between my legs, reached over and got a handful.
I had mine in the Russian room — the hottest by far, and I mean that literally. There was a cute guy with glasses (bless him; I got contacts specifically so I could cruise), and he was looking around. I made eye contact and smiled, and his dick just about quadrupled in size, thick, upward-curving, veiny. He stood up, and, with my boyfriend next to me, approached. I tried to get my hand all the way around his dick, but did my best to stroke it. I would've done more if someone hadn't walked in...
