Libido - Definition

Libido in its common usage means sexual desire; however, more technical definitions, such as those found in the work of Carl Jung, are more general, referring to libido as the free creative—or psychic—energy an individual has to put toward personal development or individuation. Libido tends to be very strong in males of all species and tends to have a low threshold for its expression. Within the category of sexual behavior, libido would fall under the appetitive phase wherein an individual will usually undergo certain behaviors in order to gain access to a mate.
