Wow, what a progressive spouse ! Like some of other responses have said, I would see what she wants first. The two of you together in a room, the two of you in separate rooms. You don't want to fall into some kind of trap on this. Make sure she is very clear on her wants and you just be guide.
@Bultaco103 has it right in my opinion, find a couples place that you feel comfortable with. Best of luck with how it turns out.
