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 or is open to engaging in either activity. 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.
