Wow when I saw the subject I actually whispered out loud ''oh, she did it!"

I've not been in your shoes so I'm in no place to say anything, since I have no personal experience. I'm actually glad you're posting about it. Anyway I'm glad you're not having any negative fall out and I hope that continues!

While I can't begin to understand your friend, it sounds like its working out for them lol. I've heard about this kind of thing before, how the occasional one night stand actually helps people's sex lives with each other. I suppose thats why "swingers" evolved.
