bi curious guy can't find a friend to try

I am bi curious. Married, wife okay with me exploring, even open to having a threesome if it goes that way. But I am unable to find a guy that suits me. I am very particular, as far as race goes (want a polynesian guy only). And we want this to not be a one night deal.

Any luck out there? Have posted on Fetlife, Craigslist, Swingers lifestyle, etc. but still nuthin.

Any luck with any other avenues? Thanks in advance!
