Mr. TwoTongues here
I've always told Mrs. TwoTongues that I'd be OK with her sleeping with women, bisexuality is part of her, and something I don't mind her exploring. We never set out to make anything happen though.
But more recently, as I said in the "How did you find the Swingers board" thread:
I think initially it bothered her that I read the Swingers board while claiming that I wasn't looking for someone else to sleep with. I encouraged her to actually read the forums, and see what they were about. That the whole point to me was to have fun and explore with your partner in complete openness. And if she doesn't want to do it, I don't want to do it. I have no interest in Swinging without her.
So she started reading the forum, and I think that once she saw that it was (largely) made up of (mostly) normal people - she felt comfortable enough to actually start to think about swinging and what her boundaries were.
And boy did things change quickly after that
She quickly went from
"Well, we can go check out the Red Rooster next time we go to Vegas" to
"Hey, maybe we could play some when we're at the Rooster" to
"Hey, maybe we could play with other people" to
"Hey, let's sign up on SwingLifeStyle" to
"Hey, I've got a date with a girl on Saturday"
Now, we're trying to do our research and find people and events in our area to learn more first, and then approach the whole thing with an open mind.
