me too. the sunday one in midtown.
went with another guy around my age.
you go in, pay, they give you a hanger, you get undressed and put all your clothes on the hanger and check them in. keep your shoes and socks on. stuff your wallet/keys/phone in your socks.
there's a water station and buckets of lube around the place. there are guys of all ages, shapes and sizes jacking off alone, in pairs, threes, circles etc. guys are respectful. will come up and play with your nipples and you can let them know if you're interested in playing. if not, they'll go find another dick - there are plenty.
there are sofas and benches if you get tired from jacking and sweating (it was summer. it was hot!)
there is a bathroom to wash your hands, pee, etc.
there is NO other play tolerated. nothing is inserted anywhere other than dicks in hands.
it's hot. anonymous. discreet.
