Question

MMF is two bi guys and female threesome
MFM is two straight guys and female threesome
Our belief

I will say that, while mfm is exclusively female to male action, mmf is generally the accepted abbreviation of any threesome involving 2 males and 1 female so don't automatically assume that if someone puts mmf the man is bi. It is always safest to ask.

I believe MMF and MFM mean the same. 2 males fucking 1 female.

I see.... so mm the the f means the guys are playing together as well as having a female to play with. The mfm is both guys only interested in the girl. Makes since. Thanks tarzanjane

I believe it's when the two males intimately interact... Somebody can correct me if I'm wrong...
