Data from a representative sample of the Spanish population (1,949 participants between ages 18 and 65) were analyzed to examine the strength of the principal romantic myths and the link between sex, love, and marriage in Spain. A survey was made up and was administered by interviewers. The results show the strength of these myths and the relationship between the three above-mentioned variables. Women, people with fewer years of formal education, and older people were more likely to believe in the myths and the relation between sex, love, and marriage was stronger in these groups. The findings are discussed in terms of different psychosocial theories.
