Yup and appears as though a lot of the guys who go to Qua are on the straightish/DL side wanting to see and be around other nude guys. Every time I’ve been to Qua it’s always been a vibe with a handful of studs roaming around. My favorite spot is the shower inside of the steam room as well as the shave room as it allows for subtle showing off and viewing. Encore and Aria also offer great spas but the layout isn’t as great as Qua’s. You’ll see a lot more shorts in Aria and Encore than Qua. From my experience at Qua, you might see a couple of guys who start out with shorts and pretty quickly they come off as they see others and get more comfortable - it’s pretty hot.
Never hooked up in any of them but just going, being nude and being around others nude is enjoyable all in itself.
