The sexual behaviors in this study aren't necessarily something to worry about, Hald said. "Some people would say they're great and introduces people to variety and improves their sex life, so we refrain from calling these bad," he said.
Participants in the study completed an online survey in 2010 about their relationship status, ethnicity and other factors, as well as about their porn use and sexual attitudes, including whether they liked wild sex and how they felt about their sexuality and being pressured to have sex.
The survey also asked participants about partner experience (including the number of partners they had, age at which they first had sex, whether they had ever had a one-night stand), adventurous sex (such as whether participants had ever had a same-sex partner or a threesome) and transactional sex (whether they had paid someone or been paid themselves for sex).
The fact that the survey was conducted online and anonymously probably lessened the chance that participants would lie about their sexual attitudes and experiences, Hald said.
The researchers found a connection between using porn and having more partner experience, adventurous sex and transactional sex for both men and women, but the association was small for both genders. Although the survey found an association, it did not prove a cause-and-effect link.
Factors such as being religious or in a relationship did not appear to affect the influence of porn use, with the exception that there was an even more modest connection between porn use and partner experience among women who were religious.
One expert said she thought the Dutch findings would also apply to the United States.
"I think that these results would be similar in the U.S.," said Susan Tortolero, an associate professor of health promotion and behavioral sciences and epidemiology at the University of Texas Health Science
