Sexual orientation is an enduring pattern of romantic or sexual attraction (or a combination of these) to persons of the opposite sex or gender, the same sex or gender, or to both sexes or more than one gender.

These attractions are generally subsumed under heterosexuality, homosexuality, and bisexuality, while asexuality (the lack of sexual attraction to others) is sometimes identified as the fourth category.

Bisexual women are significantly less restricted in their sociosexual attitudes than both lesbian and heterosexual women.

Unrestricted individuals place more importance on partners' physical attractiveness and sex appeal, while restricted individuals place more weight on characteristics indicative of good personal and parenting qualities (e.g., kind, responsible, faithful).
