Will you have a threesome with your husband/wife?

No - it's an interesting fantasy and I admit to getting off to the thought often. But the complications of actually doing it are way to emotionally perilous for me.

I have had a 3some before, but I don't think I would do one with a best friend. That could have alot of complications down the road. Not worth loosing a best friend over I don't believe.

we used to talk about this when we were dating. Changed after 3yrs of marrage

I would, if she was up for it.

There is a lot more to it besides just the sex. It really has to be the right person. Everyone involved has to have the balls to say stop if they aren't comfortable. The 'third wheel' has to be someone that the other parties won't get emotionally attached to, but still be able to see on a day to day basis, if the situation involves that. It can work. I've had quite a few of them, and it really just boils down to the chemistry and confidence between the three people.

No... too awkward with a close friend.

No, there's too much chance of it ruining our relationship.
