This article will discuss sexuality from an existentialist and constructivist point of view. Constructivism will be used as a means to grasp a dynamic understanding of sexual existence and intimate life. In fact, the author believes there is genetic character of intimacy that informs the passive and active existential choices that constitute our sexual identity. The goal of the article is to show how the social constructions that define human sexual existence are remodeled continuously by the fluid nature of intimacy.
