Emphasis is placed in the difficulty in conceptualizing sexuality as a complex and controversial subject. This is a presentation of a concept based on freudian psychoanalysis. With this in mind, many of Freud's references are collected from the Brazilian Standard Edition of the Complete Psychological Works of Sigmund Freud. The following concept is arrived at: sexuality is an instinctive vital energy directed to pleasure, with the possibility of quantitative and qualitative variations, closely bound to homeostasis, to affection, to social relations, to phases of development of childhood-libido, to eroticism, to genitality, to sexual relations, to procreation and to sublimation.
