Why is it men associate a MMF threesome (yes MMF IS a threesome) with bisexuality? I've done many of them and the two men never engaged in any sexual activity with each other....not to say they CANT but just because its two guys and a girl DOES NOT automatically mean it is
Threesome
Slang for a group of three people engaging in sex.
