What is a bi-MMF threesome?
A bi-MMF threesome is an MMF threesome (two men, one woman) in which the two men are bisexual and engage with each other as well as with the woman — not just "two straight men taking turns." Bi-MMF is a distinct subculture within the lifestyle, smaller than its FFM counterpart but with dedicated online groups and specific clubs/events that welcome it. Profile bios that explicitly note "bi-MMF interest" find each other faster than ambiguous bi-friendly tags. Etiquette and consent norms are the same as in any threesome — negotiated up front, paced together, with clear pause signals.
