Bisexual
I completely agree with you about the bisexual polyamory thing, it's practically a must have when you have urges to love both sexes, it's hard and restricting to just choose one and leave the other out of your mind for life, it just doesn't work that way. I am a bisexual female and my Fiance will fully support me if I find a woman and fall in love. It would either be two separate relationships on my end or it would be one 3-way relationship, whichever happens he is perfectly fine with and I think it takes great courage and true love to allow your lover to do something like this. It is completely unselfish and there aren't many people like that in the world.
I wish you and your wife luck in finding the perfect mate. Here's to the future!
I have always held to the rule, women bring the women, because the chatting outside of bed is very style oriented, whereas a guy just needs to know if he head is flat enough to rest his beer on when she is giving him a blow job.
Now if you are going for either the disposable gf or disposable husband ( is your father or brother a divorce lawyer?) or both, them maybe that shotgun harpoon with electric winch, (I hope solar so we can protect the environment)
If you are thinking about children, it gets messier.
I would focus on the three way style, I mean you've already infected him with your cooties and so he can touch a bisexual female without his skin on arm and face falling off like the guy in Robocop.
Now I have heard a rumor and there are some pretty sick studies going on a universities that show female bisexuals are more emotional stable and also acceptable in society. Bisexual males must vote Republican and be praying to Jesus in public bathrooms for that monkeyshines to be anywhere near OK.
But I find, if you get in this three way stuff and both of you are fucking this poor sorry bozo, you run the chance of leaving him a hollow husk, a shell of a man as it were. Now new advances in latex and rechargeable batteries, means this is not a total failure, but tends to leave on of the girls to take out the garbage
Now shopping for boys is much easier, but let the boy do the shopping, because the nuances of mixing and matching football, hockey and basketball preferences to say just having a jar of hazelnut AND vanilla coffee creamers (and a word of advice some of the early model men, I mean the non-metrosexual, have these odd notions about coffee flavored coffee, I know! So cute) but of course girls get last say, well not always, because from a practical point of view guy mowing the lawn, hung to his knee, but that guy you keep in the maids outfits with frilly pants, the one who does your TAXES he has to have a CPA.
And while strap ons have made great advances, most goils I know (yes Biblically) say two live models is even better and they can chat about football while washing your car.
