Psychologists have proven that teenagers who are exposed to Hollywood sex scenes have sex at an earlier age than those who aren’t.

The American study showed that love scenes “fundamentally influence” a teenager’s personality and attitude to sex.

According to the Telegraph, the study’s findings were based on nearly seven hundred popular films.

Researchers in Dartmouth College in New Hamshire concluded that for every hour that a teen is exposed to sexual content they are five times more likely to lose their virginity within six years.

Dr. Rose O’Hara who led the study said: "Adolescents who are exposed to more sexual content in movies start having sex at younger ages, have more sexual partners, and are less likely to use condoms with casual sexual partners.”

The study began when the participants were between twelve and fourteen years old and analysed their behaviour for a subsequent six years.

After six years the 1128 participants were asked when they lost their virginity, how many partners they had and if they used protection.

The films used in the study included Austin Powers, Notting Hill, American Beauty and James Bond films among others.

Speaking about the study, Dr. O’Hara said: “These movies appear to fundamentally influence their personality through changes in sensation-seeking, which has far-reaching implications for all of their risk-taking behaviours.”
