I knew your post would be pulled so tried to email you via your board registered addy, and that bounced.  Anyways, if this is you it seems your question has slightly changed, though I'll add my original reply in case you missed it during the short time it was up...
: )

When the woman is equally interested, it is good.  She is the key.  It "can" go wrong though rarely does when you work with a sensitive and aware provider.  Yes, you absolutely need to find out what her expectations are and share those with the provider!  

Have fun!

Original reply, if you are the same gent:
Hi there!

I hope you don't mind my emailing off your profile addy vs. responding on the board... often "couples" posts are removed, as are any ads by men or TS providers.  This is the best way to make sure you see my reply.

First, congratulations on having such an open minded loving woman in your life!  I'm always honored and thrilled to know of partners playing together!  There are several logistical considerations -

While it is great to let her choose the provider to ensure that she is as excited and comfortable with the meeting, it is difficult to arrange a "surprise."  There are too many details that must be agreed and understood for the two of you to have the best possible session time.  Of course, if you two are active swingers and have already established a very comfortable manner of communicating and negotiating situations, just ignore everything I have to say lol!

Playing with couples automatically creates a situation where the lady is outnumbered and at greater physical risk, additionally, there is a witness thus it is doubly important that both parties be screened to avoid nasty legal complications.  

I *insist* on speaking with the female before agreeing to meet couples.  There are too many instances where a woman simply goes along with what her partner desires out of fear of losing him and I will not participate in those games.  It is best that she make the call or initial email, and mention your board handle and references in that contact.  

If the two of you have not played with outside parties before, please have direct and specific conversations about boundaries.  What is ok or not in the time?  Also understand that sometimes those boundaries will change mid-session - something she thinks she is comfortable with may be uncomfortable at the time it comes up.  Excellent communication is essential!  

For the best experience possible make sure you both understand what you desire from the time.  Is she bi-curious or does she simply want to see you have the wonderful fantasy experience of two women?  If she is bi or curious, read the reviews carefully to make sure that your provider is too!  I've found out the hard way doing duos that not all ladies who say they love women, actually do.

I hope you two have a fantastic time!

Its all boring -

Book an appt - show up - its really that simple - there isnt anything to talk to anyone about -

on the Phoenix board who always hobby together. You may get some very good input from them. Their handle is DaFa.

I like when the guy is usually late or had to run out for something and she and I are all alone. Many of the couples I've been with the women were more comfortable when she and I sat down and had a glass of wine or listened to some music and soon began to dance closely. By the time the guy comes in the room, she and I have toys and clothes all over the place.

But every couple is different, I just find that getting to know the lady one on one worked for me and her and then everything was smooth sailing from there.

Have fun!
