my wife and i are looking for an escort who accomodates threesomes, she is bi curious and i am straight, what is the best way of approaching the subject, also are we looking for a needle in a haystack?

No,there are plenty of providers out there that do threesomes,not only FFM,but also MFM! Some even advertise as "women & couples welcome".But if you see a particular one that you're interested in and you don't know,ask her if she's "couples friendly".Good luck!

Be prepared for a well-established provider to ask to speak to your wife before setting up the appointment. We get so many calls from bozos and game-players-- hardly any "couples" requests turn out to be real, so most of us are very cautious. Screening may be a little more vigorius than usual, too, because LE often tries to set up as a couple.

Having said all that, no reason not to go for it and have fun! If you're in South Florida, give me  a call!
