responding to the sexual advances of boys compared with girls with no older siblings. Researchers believe this is because older siblings model gender roles, so girls with older siblings (especially brothers) may have more traditional views of what society says girls and boys should be like; girls with older brothers may believe that sexual intercourse is mostly for having children, rather than for gaining sexual pleasure. This traditional view can inhibit them from focusing on their own sexualities and desires, and may keep them constrained to society's prescribed gender roles. Social learning and the sexual self-concept Developing a sexual self-concept is an important developmental step during adolescence. This is when adolescents try to make sense and organize their sexual experiences so that they understand the structures and underlying motivations for their sexual behavior. This sexual self-concept helps adolescents organize their past experiences, but also gives them information to draw on for their current and future sexual thoughts and experiences. Sexual self-concept affects sexual behavior for both men and women, but it also affects relationship development for women. Development of one's sexual self-concept can occur even before sexual experiences begin. An important part of sexual self-concept is sexual esteem, which includes how one evaluates their sexuality (including their thoughts, emotions and sexual activities). Another aspect is sexual anxiety; this includes one's negative evaluations of sex and sexuality. Sexual self-concept is not only developed from sexual experiences; both girls and boys can learn from a variety of social interactions such as their family, sexual education programs, depictions in the media and from their friends and peers. Girls with a positive self-schema are more likely to be liberal in their attitudes about sex, are more likely to view themselves as passionate and open to sexual experience and are more likely to rate sexual experiences as positive. Their views towards relationships show that they place high importance on romance, love and intimacy. Girls who have a more negative view often say they feel self-conscious about their sexuality and view sexual encounters more negatively. The sexual self-concept of girls with more negative views are highly influenced by other people; those of girls who hold more positive views are less so. Boys are less willing to state they have negative feelings about sex than girls when they describe their sexual self-schemas. Boys are not divided into positive and negative sexual self-concepts; they are divided into schematic
