Damn laptop, hit the wrong button.
While getting into swinging is never an easy decision for most couples I think you two are going about it just right, taking the time to talk about it and getting your feelings and thoughts out in the open. As others have stated finding a unicorn is not easy to do but the hunt is half the fun, well more than half, and it does happen.
Make your rules and then start your search. Join a few different web sites. Look around and see whats available in your area. Go to some meet n greets, talk to the people there, get comfortable. No one is going to pressure you to play, just make sure that the people you talk to know your boundaries.
When you do find what you are looking for, make sure that you talk after and see if you are both comfortable with what has happened and then go from there, you may need some rule changes, or you may decide that it isn't for you at all. If either one of you wants to stop then by all means stop. you can always come back later if you decide to.
In our experience once you get started you will expand what you are looking for. If it's only fmf now, in the future you may feel comfortable enough to try soft swing with a couple, or even MFMF full swap. The key is to take things slow and see what you are comfortable with.
We have seen what we call "Unleash the beast" many times. Thats where the more reluctant side of a couple, once they have been exposed to the fun that can happen becomes the driving force. They are now the one who takes over the looking and planning, they are the ones who push the boundaries. This is usually the female half but in your case it will be the male. To tell you the truth we like to see this. It brings a couple to the same level and is good for both of them.
