OMG this place is crazy :p Never before have i seen so many hot guys in one place wanting/having sex.
I lined up for about 30 min, the entrance staff were polite, take your money then give you a numbered card which you must not lose! and is used for drinks so you don't have to carry money, then you walk to the change room where you take a plastic bag to put your stuff in.
No dress code when i went on Friday during Folsom but next to everyone was in hot leather gear. I chose to wear just my underwear and that was fine.
The whole place is huge with lots of places to have sex, just don't expect private rooms. Have fun and let others watch you :) Most guys move on to find someone else when you decline their advances so it's not a problem. There are two bar areas and by 3am the place was packed with so many guys having sex everywhere! The toilets are interesting with many guys sitting next to the urinals...i guess they wanted some watersports action. There was a line though for the few toilet stalls as you can imagine with hundreds of guys drinking.
Safe sex is your decision, so take condoms/lube with you. Most guys i saw had safe sex. And it was hot to watch :)
Best way to describe this place is "raw", not as in unsafe sex, but down to earth masculine guys having their primal instincts for sex being satisfied. The place is dark with candles around for lighting, cameo nets and benches for cruising, metal bars and cages with slings for dividing up areas, wooden planks for some areas, truck tyres in others, its amazing!
If you like the idea of dungeons and hundreds of hot guys you'll love this place. It's more a place for quantity rather than quality, sex is fast hot and sweaty. Not a place for princesses and tantric sex.
The guys are hot, the place is perfect, drinks are reasonably priced, it's a place to check out at least once.
