Some worry that if society disconnects intimate sexual behavior and emotional connection, teens who hook up will have trouble forming stable intimate relationships later in life.Journalist Sabrina Weill asserts that "casual teen attitudes toward sex—particularly oral sex—reflect their confusion about what is normal behavior," and adds that they "are facing an intimacy crisis that could haunt them in future relationships.
One study has found that the strongest predictor of hookup behavior was previous experience hooking up.
A hookup culture is one that accepts and encourages casual sexual encounters, including one-night stands and other related activity, which focus on physical pleasure without necessarily including emotional bonding or long-term commitment.
Adolescents, emerging adults, men and women engage in hookups for a variety of reasons, which may range from instant physical gratification, to fulfillment of emotional needs, to using it as a means of finding a long-term romantic partner.
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.
