perhaps a good place to start would be a club therfore you are in control and only have to play with each other if she really is not interested in having another join in .... if the mood takes her then invite another into the room. kind of better than getting someone around and she really only interested in the fantisy of another joining in. whatever happens tho good luck
I think the key isnt to rush it and and actually talk about it, and i dont mean during the throws of passion talk about doing other people try and talk about it seriously about it and the feeling around it outside of the bedroom when the you both arnt tearing each othe clothes off in throws of passion.
Dont try and push her into somthing she might not feel comfortable about, keep the communication up. Me and my partner, i guess are a little like you in the sense we've spoken about all the fantasies and played with the idea of exhibitonism etc etc but as for actually talking about doing it seriously we're both just arnt comfrotable with that now, for now we both enjoy flirting with the idea sometimes and it is certainly is exciting enough.
Just talk about everything dont feel the rush to do somthing suddenly or rush into it.
A rope and an oak beam would be the best way to get my wife (ex) to swing! :twisted:
