So the wife and I continue to talk about our shared fantasy of having a threesome. We're currently closed and she hasn't had any other partners in 16 years, I haven't been with anyone else ever...

She's made some comments as of late suggesting an FMF threesome and wanting to watch me with another woman. While these comments aroused me, it also confused me. While she's had some slips, gotten drunk and maybe made out with a few of her friends, I've not even kissed another woman in 16 years years. How the hell could she or I know, we could be comfortable with this? Is this just situation where we have to throw caution to the wind and see what happens or is there a way for us to test these waters before diving head first? I obviously don't feel comfortable exploring this without her presence or content but I also can't ask her to let me try making out with or flirting with someone else.

We've been together since we were teenagers in high-school. Other than our conversation into threesomes, i dont really fantasize about other women and dont really have a desire to hook up with others. I do however, share this fantasy with my wife and think it'll be a fun experience to have with her. I just don't know where to start...
