One 2011 study surveyed young adults about their emotional reactions after sexual encounters, finding that men reported more positive and fewer negative emotional reactions, and both men and women reported that the experience was largely more positive than negative.
A 23-year study in a Human Sexuality class investigated gender differences in men and women’s reactions to their first sexual experience.
According to a 2001 UNICEF survey, in 10 out of 12 developed nations with available data, more than two-thirds of young people have had sexual intercourse while still in their teens.
In Denmark, Finland, Germany, Iceland, Norway, the United Kingdom and the United States, the proportion is over 80%.
An international online sex survey compared responses of residents of 37 countries against World Economic Forum figures for gender equality in those countries, finding that countries with high gender equality had respondents report more casual sex, a greater number of sex partners, younger ages for first sex, and greater tolerance of premarital sex.
Different ethnic and cultural groups in America have varied religiosity and sexual attitudes.
Starting in the 1920s, and especially after World War II, premarital sex became more common; this was especially prevalent among women.From 1943 to 1999, attitudes toward premarital sex changed such that young women’s approval increased from 12% to 73% and from 40% to 79% among young men.People’s feelings of sexual guilt also decreased during this period.One 2006 study that analysed the Toledo Adolescent Relationships Study found that more boys report having non-dating sexual partners than girls.Of this sample, a third of boys only have had sex with their romantic partner, another third of boys who have had sex with a partner they are not dating within the past year are believed to wish for the girl to be their girlfriend.In Australia, the United Kingdom and the United States, approximately 25% of 15-year-olds and 50% of 17-year-olds have sex.In a 2005 Kaiser Family Foundation study of US teenagers, 29% of teens reported feeling pressure to have sex, 33% of sexually active teens reported "being in a relationship where they felt things were moving too fast sexually", and 24% had "done something sexual they didn’t really want to do".Premarital sex is sexual activity practiced by people before they are married.Historically, premarital sex was considered a moral issue which was taboo in many cultures and considered a sin by a number of religions, but since about the 1960s, it has become more widely accepted, especially in Western countries.In the earlier years of the study, men reported more pleasure and greater anxiety than women, while women reported more feelings of guilt than men.Cohort studies carried out over 23 years found that in later years, women expressed greater pleasure and less guilt.
