threesome

adj. pertaining to a group of three

n. group of three persons or items

A threesome is the term which describes a sexual act involving three people, also referred to as a ménage à trois. To clarify the roles, a threesome does not have to mean that all three people are engaging in sexual activity specifically with all people in the threesome, but can be one person as the focus of attention (two men focusing on one woman, two women focusing on one man, etc.), and the other two engaging in sex with the same one person, but not necessarily with each other. However, all people are together in the same location during the experience. Some people think that when two men are with one woman that the men must somehow be bisexual, but this is often not the case. Instead, they just jointly participate in the threesome, both focusing on the same one woman.
