How should I tell my wife, or should I never tell her?

My wife and I tell each other pretty much everything, even if it's uncomfortable and embarrassing, we both know the other person's sexual history as well as our deepest darkest fantasies (mine are darker than hers) with the exception of one thing. I've always been curious about experimenting with another guy, I'm mostly interested in giving another guy a blow job but I'm very open minded. I feel like she must be at least a little bit aware of my bi-curious tendencies because of other things I've suggested (pegging, having an mfm threesome, sharing/watching her with other guys, including cleaning up a cream pie) but I've never come out and told her. And I'm wondering if I ever should and if so, how should I do it?
Updates:
- Hmm. Check this book out and see if it might help. It talks about how common it is and ways to incorporate things for both partners that can add to the experience. Maybe there will be something you can use in it to open discussions.
