A sexual orientation in which a member of both sexes must be present in addition to a dual-sexual individual in a sexual scenario for that dual-sexual individual to become sexually aroused. Members of both sexes do not need to participate, but simply be present. For example, a dual-sexual individual could be intimate with a woman, but only if another man is present. This other man could simply sit in the corner and read the newspaper, but so long as he is there the dual-sexual individual will become aroused.
