Sexual Satisfaction in Spanish Heterosexual Couples: Testing the Interpersonal Exchange Model of Sexual Satisfaction.

The study of sexual satisfaction in Spain is scarce and has proceeded atheoretically. This study aimed at examining sexual satisfaction in 197 Spanish heterosexual couples based on the Interpersonal Exchange Model of Sexual Satisfaction. Men and women reported equal satisfaction. Men's sexual satisfaction was predicted by their own relationship satisfaction, balance of sexual rewards and costs, and comparison level of sexual rewards and costs. Women's sexual satisfaction was predicted by their own relationship satisfaction, balance of sexual rewards and costs, comparison level of sexual rewards and costs, equality of sexual costs, and their partner's balance of sexual rewards and costs. These results provide with a better understanding of the mechanisms that explain sexual satisfaction in Spanish couples. Implications for research and therapy are discussed.
