Sex, Anyone?

Human sexuality is always fascinating, yet often we rely on vague impressions rather than scientific observation and systematic data. When we look at the facts, we find that some of our perceptions are rather inaccurate.

In the first comprehensive global study of sexual behavior, British researchers found that people aren’t losing their virginity at ever younger ages, and that married people have the most sex.

Professor Wellings of the London School of Hygiene and Tropical Medicines and her colleagues analyzed data from 59 countries. Wellings said she was surprised by some of the survey’s results: "We did have some of our preconceptions dashed." Experts say the study will be useful in dispelling popular myths about sexual behavior.

The study also found that contrary to popular belief, sexual activity is not starting earlier. Nearly everywhere, men and women have their first sexual experiences in their late teens — from 15 to 19 years old — with generally younger ages for women than for men, especially in developing countries. That is no younger than 10 years ago. In every country, teens are choosing keep their virginity longer. This surprised researchers, because the common media image presented to the public is that of young people failing to keep their virginity. "There's a big disconnect here," commented one scientist, "between real life on the one hand, and the world of TV and movies on the other hand."

Researchers also found that married people have the most sex, reporting engaging in sexual activity in the previous four weeks more frequently than single people. There has also been a gradual shift to delay marriage, even in developing countries. Married people also report greater satisfaction in their sexual activity, both physical and emotional.

A follow-up study, conducted by sociology professor Armour at Ohio State University, explains why some of these surprising trends are taking place: Teens who lose their virginity earlier than their peers are more likely to steal, destroy property, shoplift or sell drugs than their virgin counterparts. The study, reported in the Journal of Youth and Adolescence, found that those who had sex early were 26 percent more likely to be in trouble than those who waited, even years after their sexual debut and well into early adulthood. Those who had sex later had delinquency scores 20 percent lower than their peers. Waiting had a protective effect.

"Students in high school and college are watching their peers and learning," said a researcher. "They see what happens to others choose to keep their virginity a while longer, because they don't want to endure those same negative consequences."
