Three-Way

Also known as a Threesome is a form of group sex involving three people of any gender combination.

Some people have made the argument that if the act does not involve sexual involvement between all three members that it is not a threesome at all and could be more accurately called a double team. This would be when two members of the threesome engage with one person but not actually with each other.

Types:

Group Sex- is when sexual intercourse and/or anal sex are performed on the woman/man by two men in a double penetration. Another form of threesome is when a man/man is given either intercourse and/or anal sex by one man (doggie style), while he gives the second man oral sex. Yet another example is a woman and woman perform vaginal sex (using a strap) from behind or reverse cowgirl, while a third person performs oral sex on the woman (clitoris)

Ménage à trois- The term threesome should not be confused with the term ménage à trois, although both activities involve sex among three people.

Triad- It is most commonly used to describe a love relationship between three people where it can either take the form of a triangle (in which all three people have a love relationship with the other two) or a "V" (in which two people independently have a love relationship with a third). Typically this type of relationship is a form of an open relationship in which the couple seeks to incorporate a third person equally into their relationship. It is a kind of polyamorous relationship.
