This process leaves young girls unassertive about their own sexual desires and needs because they focus so much on what other people expect of them rather than on what they feel inside. Another way gender roles affect adolescent sexuality is through the sexual double standard. This double standard occurs when others judge women for engaging in premarital sex and for embracing their sexualities, while men are rewarded for the same behavior. It is a double standard because the genders are behaving similarly, but are being judged differently for their actions because of their gender. An example of this can be seen in Tolman's research when she interviews girls about their experiences with their sexualities. In Tolman's interviews, girls who sought sex because they desired it felt like they had to cover it up in order (for example, they blamed their sexual behavior on drinking) not to be judged by others in their school. They were afraid of being viewed negatively for enjoying their sexuality. Many girls were thus trying to make their own solutions (like blaming their sexual behavior on something else or silencing their own desires and choosing not to engage in sexual behavior) to a problem that is actually caused by power imbalances between the genders within our societies. Other research showed that girls were tired of being judged for their sexual behavior because of their gender. However, even these girls were strongly affected by societal gender roles and rarely talked about their own desires and instead talked about how "being ready" (rather than experiencing desire) would determine their sexual encounters. O'Sullivan and her colleagues assessed 180 girls between the ages of 12 and 14 on their perceptions on what their first sexual encounters would be like; many girls reported feeling negative emotions towards sex before their first time. The researchers think this is because adolescent girls are taught that society views adolescent pre-marital sex in negative terms. When they reported positive feelings, the most commonly listed one was feeling attractive. This shows how many girls objectify their own bodies and often think about this before they think of their own sexual desires and needs. Researchers found that having an older sibling, especially an older brother, affected how girls viewed sex and sexuality. Girls with older brothers held more traditional views about sexuality and said they were less interested in seeking sex, as well as less interested in
