An MFM threesome is sexual activity between three people, two of whom identify as male and one who identifies as female. The arrangement of the letters in the acronym, MFM, is important in this context because it signifies that the male participants are not interested in sexual play with each other, that they are solely interested in engaging sexually with the female participant.
Threesomes can come together from a variety of circumstances and relationship configurations. All partners must enthusiastically consent and agree to what activities are on the table and what each person's limits are.
All three participants can be strangers or just casual friends. One male and one female can be in a relationship and invite a second male (stranger or friend) to join for specifically sexual reasons. Sometimes the female is in a Vee relationship with both of the male participants.
Although MFM denotes that there is no sexual contact between the male participants, they must both be comfortable with another close male presence. Different opportunities for focus and pleasure are available when three people join together for sexual play. During MFM threesome sex, focus is often on the woman, with the woman focusing her attention on both of the men equally. It can also play out as a cuckolding scene where one of the men and the woman are the featured (or only) players, while the other man watches or has limited engagement with the woman.
Many different sexual positions and activities can be used with three people in an MFM configuration, involving manual, oral, vaginal and anal sex. Some popular positions include double oral connections (one man provides oral sex for the woman while she also provides oral sex for the other man), (the woman provides oral sex for one man and has vaginal or anal sex with the other) and double penetration (the woman is penetrated by the two men simultaneously, one vaginally, anally or orally). A safeword is important and if there will be oral sex, gagging, or any kind of activity where verbal communication will be impeded, agree also on a safe gesture.
There are also many opportunities to include different types of sex, including BDSM and fetish play into MFM threesome sex, always ensuring every act and every second is safe and consensual.
MFM threesome is short for male-female-male threesome.
