Topping from the bottom

In human sexuality, top, bottom and versatile are sex positions during sexual activity, especially between two men. A top is usually a person who penetrates, a bottom is usually one who receives penetration, and a versatile engages in both activities. These terms may be elements of self-identity that indicate an individual’s usual preference, but might also describe broader social, psychological, or sexual identities.

Top, bottom and versatile are also used in BDSM to describe similar—but distinct—BDSM identities and practices.
