For example, a study of Canadian college students who planned to hook up while on spring break showed that 61% of men and 34% of women had sex within a day of meeting their partner.
Another study was based on a survey of over 18,000 college students from ages 18–25.
This survey asked questions like how many sexual partners they have had since graduating high school, how many sexual partners per year, and how many times per week they have sex.
It was reported that a little over 59% of college students have sex once per week.
Subculture can affect gender roles and sexuality, and youth subcultures are particularly susceptible to peer pressure.
Self-esteem is also an indicator: men with high self-esteem and women with low self-esteem are more likely to have multiple sexual partners, but hookups are less likely among both genders when they have high self-esteem.
A hook up is an act that involves sexual intimacy, claimed by many to be a sexually liberating act.
On the other hand, hook up culture is thought to be oppressive and monolithic, with intimacy only occurring within a specific context.
Young women tend to be honest about their sexual encounters and experiences, while young men tend to lie more often about theirs.
Another study shows that once a person has sex for their first time, it becomes less of an issue or big deal to future relationships or hook ups.
For some adolescents, sex and relationships have been decoupled.
