But, on the contrary girls will have sex with their partner in order to match them.For some adolescents, sex and relationships have been decoupled.Studies have shown that most high school girls are more interested in a relationship compared to high school boys, who are mostly interested in sex.Young women tend to be honest about their sexual encounters and experiences, while young men tend to lie more often about theirs.These developmental shifts, Garcia's systematic review of the literature suggests, is one of the factors driving the increase in hookups, a "popular cultural change that has infiltrated the lives of emerging adults throughout the Western world." The review shows that hookups are becoming increasingly normative among young adults and adolescents in North America and have taken root throughout the Western world, which represents a notable shift in how casual sex is perceived and accepted.Garcia and others have noted that the "past decade has witnessed an explosion in interest in the topic of hookups, both scientifically and in the popular media.Research on hookups is not seated within a singular disciplinary sphere; it sits at the crossroads of theoretical and empirical ideas drawn from a diverse range of fields, including psychology, anthropology, sociology, biology, medicine, and public health." The hookup culture is vaguely defined due to a variety of perspectives taken on this subject related human sexuality.
Subculture can affect gender roles and sexuality, and youth subcultures are particularly susceptible to peer pressure.
People are marrying and beginning families at ages later than previous generations while becoming sexually mature at an earlier age.

During the twenty-first century paid sex was not considered to belong to the category of casual sex; however, in the 1900s-1930s there was more to paid sex than simply the exchange of money–it was a contact between humans without the ties of a relationship.
Technological advancements such as the automobile and movie theaters brought young couples out of their parents' homes, and out from their watchful eyes, giving them more freedom and more opportunity to engage in sexual activity.
