I had one of those things one time, but I was the only one who took his clothes off - I kind of felt foolish
I would like to do one when we all get nekid

I've never tried but would be willing to go either MFM OR FMF.

I used to think it would be the ultimate thrill, but I'm having such a good time in the sack with my wife that it is not even on my mind. Unless she brings it up... FMF!

I have always thought it would be fun with another chick in the bed, but 1 on 1 sex with my girlfriend has never lacked anything, and I don't think she'd be keen with the idea. Plus, I don't know any other girls that would be good possibilities even if there was a chance of it happening.
I guess the solution to the riddle of whom to cum in is to not cum in either - just spray it all over both of them. If the three way is just going to be in my imagination, I can get away with that I guess.

I've seen quite a few people say this in this thread and it makes me happy that I'm not the only guy who thinks this way.

I don't think I could every do a threesome with my wife, but there was this time back in high school when I had some fun one evening with two best friends. The best part of it was that it was completley unexpected.

I once had the chance, FMF. I had to refuse, due to my ex was psycho (Norman Bates ring a bell?) and I broke it off. She tried suicide and various other ways to get me back. And one was trying to tempt me back to the relationship with a FMF. I was so tempted. But, I had to get her out of my life so at any cost! It was the hardest thing I had to say "NO!" to in my life! I still think about it to this day, and wonder what would have it been like, and who(I live in a small town!) But, you get to a point in your life you just can't do the "What if's?"

Always a fantasy of mine but when I actually got to do it it wasn't all that. Kind of akward and mechanicl but maybe I just had a bad experience. Part of the fantasy is being able to move about but I had to change condoms each time and that kind of slows the momentum. And that's just from a physical perspective. Emotionally its a big can of worms that isn't worth opening.

? for all of those who responded with tried it once.. wasn't a good idea. Why did it not work out? Was it because it was not fully discussed beforehand? Did you really want it or were you just trying to satisfy a partner's fantasy? I've been thinking about this for a while now (MFF... don't think I'd be interested in another guy other than my b/f) and I've heard many neg. comments about it. My b/f has done it before but not with a g/f. I've never done anything in this field but am very curious...

Yes if it was two chicks that i wasn't emotionally attached to. But NEVER with a gf or wife, too much to lose with little gain other than bragging rights and a couple hours of pleasure.

I would do a FMF or a FFF, but I really don't think I would enjoy a MFM. This is for 2 reasons: 1) I'm not turned on by two guys doing stuff to each other 2) I'm too fucking lazy to put out double the effort for guys :)

Almost had a FMF in college, but we all sort of chickened out. I have to say I am glad, because I married one of the girls and I just don't know how things would have worked out if we had. The other girl and I had dated briefly, and while my wife and she were really good friends and still are, it has always bothered my wife that the other girl and I dated. Imagine if we had gone through with the tois. I agree with most of ya, you have to be careful if you do it.

I've done it a few times and it's pretty cool..nothing like the two women on one guy..whom I was married to...seeing him be pleased, the look on his face and vice versa is pretty erotic!
