FMF

Three letters that tell you in advance who focuses on whom during a threesome.

What is FMF?

FMF (Female-Male-Female) is a threesome with two women and one man, where the two women do not touch each other. The letters stand for the arrangement: because the M sits in the middle, there is no sexual contact between the women. The man is the pivot, and both women focus on him.

Not to be confused withFFM (women do go together) and MFM (two men, one woman)
Core pointthe arrangement is agreed in advance, not automatic

How the letters work

The order of the letters tells you who is with whom. According to the swinging scene, the simple rule is to look at the letter in the middle, because that is the person all the attention is on. When two identical letters sit side by side, like the FF in FFM, there is usually sexual contact between those two. In FMF the M keeps the women apart: no contact between them, both focused on the man. So three letters already tell you roughly how the evening is meant to go.

Why people choose FMF

FMF is one of the most common fantasies, especially among men. For the man it means two women focused on him, without having to choose. For women who have no wish for sex with another woman, FMF is a way to share something together without it becoming bi. Ashley Thompson and colleagues showed in Archives of Sexual Behavior (2021) that interest in and experience with mixed-gender threesomes among adults is widespread, often driven by curiosity. The three letters are only a starting point. What actually happens you agree in advance, and jealousy and boundaries deserve just as much attention as the arrangement.

What I see myself

In the threesomes I take part in, what strikes me is that the agreement over who touches whom matters more than people expect beforehand. A letter on paper does not take the nerves away. So I keep asking: what do you want to see, and where is your limit. Once that is clear, the rest relaxes on its own. If you want to arrange a threesome like that together with me, the page on couples explains how I approach it.
