Finster ol' dude, I'm probably going to get flamed for going against the grain here, but as we all know, that's never stopped me before...
I would think long and hard before telling your wife about your bisexual episode, whether you ever try it again or not.
Along about now, the usual suspects will jump up and start screaming about how you would be "cheating", "lying", etc, ad nauseam. Bullshit. There is a much bigger issue at stake here.
The question you have to ask yourself is, knowing your wife as you do, is she going to handle this bit of news well? Or is she more apt to go apeshit over it, with the result that your marriage crashs and burns on the spot?
The thought processes of the average woman's mind are mysterious and not to be understood by mortal men, particularly in the area of territoriality, not to mention sexuality, especially as it applies to bisexuality.
(Women have a very strong territorial imperative; in some ways even stronger than men. And sexuality is so wrapped up in emotion and easily bruised egos, particularly with women, as well as a frequent inability to understand sexual yearnings not their own that, between the two, you are looking at one fuck of a powerful and touchy time bomb. This is NOT something you want to diddle with lightly.)
The landscape is littered with the broken carcasses of marriages where the man was bi or bi-curious and just had to come clean with the little woman, who promptly went ballistic and left his ass, or at the very least made his life a living hell of suspicion, innuendo and accusation.
To see how skewed society's views are on this subject, you need look no further than the swing lifestyle. Where women are concerned, it is perfectly OK for the women to be bi or ci-curious. Indeed, it's become a cliche of sorts. But in most cases, if the male is bi or bi-curious as well, they will run into all sorts of problems, often to the point of being ostracized by some people and groups. Happens all the time, even in a supposedly "open-minded" community such as swingers are purported to be.
And it's not just the guys who get froggy over the issue; quite often the women do as well, even if they themselves are bi. Hypocritical? Yes. Double standard? Bet yer ass. Unfair? Yeppers, but sorry, life is not fair. Deal with it.
I'm going to assume you and your wife are the typical family, with 2.3 kids, 3/2/2 house with mortgage, SUV in the garage, etc. What you have to ask yourself is whether imparting this information to your wife is going to put all this at risk, and if so, is it worth it?
If you are at least reasonably sure she can take this news with equanimity, then fine. Tell her and go in peace. But if you think she is more likely to come unglued over this, then my advice is to keep your own counsel and drop it. Just chalk it up as an interesting experience and move on. It is not worth risking your marriage and family over.
