I can relate to your concerns. I am married and extremely down low. That being said, I have had plenty of experiences in these spas. I have never been to Luxor spa, so I can’t speak to it. Mandalay Bay and Qua at Caesars are extremely cruisy and never disappoint. My advice is keep your options open and be willing to see what happens. At a minimum, you can enjoy hanging out nude in the lounge chairs, hot tub, sauna and steam room. If you see someone you like, follow them to whichever they go and strike up a conversation. In Vegas, it’s always “where are you from” and “are you in town for business or pleasure”. Most guys will have a towel over their junk in the sauna or steam. I recommend it at first. I keep mine draped loosely over one leg. That way, if I’m interested, I can spread my legs and let it drop. Most guys will signal their interest by tapping a foot, dropping their eye contact to your crotch or scratching their balls or giving their dick a tug. If they do, you can mimic their action to let them know you are interested. When walking from spot to spot, wrap a towel around your waist. Keep a towel handy so if you get a boner, you can cover it up if you don’t want to send the wrong signal. If someone gets the wrong message and thinks you are interested when you aren’t, just walk away. If they keep following you, just say “ sorry man, not interested”. I’m not exactly a 10 and am now in my later 40’s but still seem to find reliable action in spas. Since covid, if there aren’t many people there, just plan on staying for several hours. At some point someone will come in and there is a very good chance they are there for the same thing you are. If nothing else you can get good rest on a lounge chair. Sometimes I lay there nude and sometimes I wear a robe or have the towel draped over me. It just depends on the foot traffic and what others are doing. Good luck and let us know how it goes.
