sociosexual orientation
a dimension of personality that describes people’s comfort with and preference for sexual activity in the absence of love or commitment. People who are said to have an unrestricted sociosexual orientation (usually but not exclusively men) report more sexual activity outside of committed intimate relationships (e.g., one-night stands, short-term relationships, extramarital affairs). In evolutionary theorizing, sociosexual orientation is considered a determinant of preferences about the enactment of short-term versus long-term mating strategies.
