Personal lubricants (colloquially termed lube) are specialized lubricants used during human sexual activity to reduce friction between body parts, or between body parts and other objects. They are used during sexual acts such as intercourse and masturbation, to reduce friction to or between the penis and vagina, anus, or other body parts, or applied to sex toys to reduce friction or ease in penetration.
