I can personnaly recommend in terms of swingers clubs the 'green door', the 'red rooster' is a little out of the way and just doesn't have the vibe.
Now if you want to share exculisivly with BBC at the club well just turn away third advances if you in fact get any, as it's not really a meat market atmosphere in these clubs. If you want the club to themed towards BBC, they may do a night like that but it won't be exclusively BBC.
Otherwise there's AVN coming up in less than a month, we'll be in Vegas for it and we can make some intros for you to other Ho's that we know (pun intended). They live in Vegas and you can possibly join their private parties when they do them.
If you need more info or specifics just PM or message me and I'll answer.
