So my girl has really started seeming like she is coming around to the idea of MFM more and more. We have a potential third in mind and I can tell she has been opening up to the idea by the way we talk about positions and fantasies and what it would be like during sex... We see him from time to time and last time She was a little flirty with him when we all hung out... And even said we should invite him for a dinner night. I've joked about it with the guy before as well and he is definitely down. My question is how do you prepare the guy for the situation? What are all the expectations, likes and dislikes, and other stuff you discuss with him before making the leap? I don't wanna miss or forget anything I should address. I don't think he's ever done something like this before either so what do you all do to help build the excitement and anticipation with your wife/gf and also with the third?
