Sex and Sexuality

Sex: a process composed of several levels that make each person unique and unrepeatable. Sexuality: the way each person perceives, feels, and lives their own sex.

Dimensions of Sexuality

• Biological characteristics: anatomical, physiological, and endocrine features that differentiate men and women.
• Psychological dimensions: emotions, feelings, beliefs, and values associated with each individual; personality, thoughts, desires, and identity are key factors.
• Values and ethics: every society shapes development and expression of sexuality, establishing values and guidelines that influence behavior.
• Clinical factors: problems such as anxiety or depression can cause psychological issues that affect sexual life and cohabitation.

Role of Sexuality

Body contact: physical contact conveys feelings and emotions. Nonverbal communication: nonverbal language is often more spontaneous and sincere than verbal language.

Pleasure: feelings of pleasure and displeasure are among the first experiences humans have and are essential for personal development. Pleasure results from a rewarding relationship with oneself and with others.

Continuity: sexuality is a constant aspect of individuals' lives; reproductive capacity is reduced at certain ages.
