How would you reply to a couple looking for mmf?

Just so you know...a MMF threesome involves bisexual men. A MFM is where there is no sexual contact between the males.

 

Excellent. I do love it when someone knows the correct usage of the terminology.

 

Yes I have seen this argument on swingers sites before and many others are like myself and don't think it really makes a difference what order the letters are in! If you are clear that there will be no man on man then people get it.

 

I never knew there was a difference in terminology. Interesting.

 

It just helps everybody be on the same page. That's all.
