Societal attitudes toward Homosexuality vary greatly in different cultures and different historical periods, as do attitudes toward sexual desire, activity and relationships in general. All cultures have their own values regarding appropriate and inappropriate sexuality; some sanction same-sex love and sexuality, while others may disapprove of such activities in part. As with heterosexual behaviour, different sets of prescriptions and proscriptions may be given to individuals according to their gender, age, social status and/or class.
