Sexuality is an expression that an individual chooses for themselves. It is how we understand our bodies, gender identity, sexual orientation, expression and intimacy levels. Sexuality is unique, diverse and always evolving. Sexuality is not about sex but about the understanding of yourself and learning more about your feelings physically, sexually and emotionally.
