Sexual orientation and sexual identity are closely related concepts in adolescent development, but they are not the same. Both are important aspects of human sexuality and contribute to an individual’s understanding of self, relationships, and social experiences. Sexual orientation mainly refers to patterns of emotional, romantic, and sexual attraction, whereas sexual identity refers to how an individual understands, labels, and expresses their sexuality. Sexual orientation describes the direction or pattern of a person’s emotional, romantic, or sexual attraction toward others. A person may experience attraction toward people of the opposite sex or gender, the same sex or gender, more than one gender, or may experience little or no sexual attraction. Common terms used to describe sexual orientation include heterosexual, homosexual, bisexual, and asexual. Sexual orientation is concerned primarily with whom a person is attracted to. It is not determined simply by a person’s behavior, because attraction, behavior, and identity may not always correspond. Sexual identity, on the other hand, refers to the way an individual personally understands and identifies their sexuality.
