Sexual orientation refers to the emotional, romantic, or sexual attraction one feels toward others. It can include orientations such as heterosexuality, homosexuality, bisexuality, and others. Understanding sexual orientation helps individuals recognize their feelings and relationships with others. Gender identity is a person's internal sense of their own gender, which may be male, female, or something else entirely. It may or may not align with the sex assigned at birth. People may identify as cisgender if their gender identity matches their assigned sex, or as transgender if it does not.
