Resumen
In the last decades, studies with sexual selection in the human species have turned their
attention to individual aspects, such as: self-esteem, sociossexuality, personality, and
attachment. Self-esteem is a social thermometer that indicates to an individual when he must
change their behavior. Sociossexuality can be defined as a behavioral tendency of one person
engage in casual sex. Personality is a set of psychological traits defined by the interaction
between genetic predisposition and environment. The romantic attachment can be described
as a set of behavioral tendencies that allow the individuals maintain emotional bonds. The
aim of the present study was to investigate the relationship between self-esteem,
sociossexuality, romantic attachment, personality, self-perceived mate value, idealization of
a romantic partner and relationship satisfaction in heterosexual and non-heterosexuals
individuals. 385 volunteers participated in this study, 219 singles and 166 in a long-term
relationship (12 months or more of duration). The participation consisted in answer a package
of questionnaires. Our results showed that heterosexual and non-heterosexual men and
women differ in their idealization of a romantic partner, and self-esteem influence the
idealization of a romantic partner. On the other hand, self-esteem does not differ between
single and committed participants. The sociossexual orientation, the personality traits and the
attachment dimensions are different between sex and sexual orientations. Also, the romantic
attachment and personality traits could predict the self-perceived mate value and the partners
evaluation of the individual’s mate value. The romantic attachment was the most capable of
predicting relationship satisfaction when compare to the other studied variables. We suggest
that the evolution of self-esteem, personality, sociossexuality and romantic attachment could
have influenced the mate choice context.
