A video game is a powerful motivator.
So why would you want to avoid a video game like Call of Duty or Destiny?
The answer, according to a new study, is that you want sex more.
In fact, the researchers say the porn-addiction question can’t be answered without exploring how sex is affected by the game.
In a study published this month in the journal Psychological Science, researchers at Columbia University in New York, Columbia University’s Graduate School of Journalism, and the University of Southern California surveyed 1,097 men and women, who played the popular Call of Dutys multiplayer video game.
Participants rated their sexual behavior on a scale from 0 to 9 (with 0 representing the most “interested” and 9 representing the “most negative”).
Among the more interesting findings: For the men who played Call of the Duty, there was an average increase in “sexual pleasure” over time, with “sex-related desire” growing from about 30 minutes in the first week to more than 30 minutes by the end of the study.
But for the men playing Destiny, the increase in sexual pleasure was smaller, at about 5 minutes per week, and “sexual desire” fell from more than 20 minutes to about 12 minutes per month.
And for the women, the sex-related desires fell from about 10 minutes to less than 10 minutes per day, with no significant change in the “sexual arousal” score.
“This study indicates that women are less likely to be sexually satisfied with a game if it has a violent content,” said David Ley, an assistant professor of psychology at Columbia who led the study and was not involved in the research.
“That’s consistent with what we’ve seen before with the game industry,” Ley added.
“It doesn’t have to be violent.
It can be erotic.”
For the researchers, the findings add to a growing body of research showing that porn users are less satisfied with their relationships than their peers.
In one 2014 study, researchers found that men who were exposed to porn reported poorer sex lives.
A 2012 study found that women who watched porn were more likely to suffer from post-traumatic stress disorder than women who didn’t watch porn.
And a 2011 study found pornography use among college students increased over time.
For men, the relationship between pornography and poor sex lives is not necessarily an academic question.
Studies have found that people who are more sexually active tend to be more likely than non-active men to have poor sexual experiences, according the researchers.
And research published in the British Medical Journal in 2009 showed that porn use is linked to poor health, depression, and suicide among women.
But in the current study, the men in the study were less likely than their female counterparts to use porn, and they were less sexually satisfied than their non-porn peers.
And when the researchers analyzed their data for men, they found that for men who used porn, the number of porn-related sexual partners dropped from 4 to 1 over time and the number who watched the porn decreased from about 12 to about 3.
That’s a trend that has been shown in a 2012 study from Johns Hopkins University, the same university where Ley is a professor of psychiatry.
In that study, men who had been exposed to pornography reported fewer sexual partners over time compared to men who didn, or didn’t.
Ley and his colleagues also found that those who viewed porn for the first time were more than twice as likely as those who hadn’t to report having an erection in the past week, according that study.
That finding is consistent with research showing porn can have a negative effect on erectile function.
But porn isn’t the only factor that can affect sex lives, said the study’s lead author, Michael Coyle, a doctoral candidate at Columbia and co-author of the 2013 study.
Porn can also negatively affect women’s sex lives as well.
A 2014 study from the University, at the University Health Network in New Orleans, found that sexual harassment and stalking were more prevalent among women who had watched porn.
Coyle and his team also found higher rates of depression among porn users.
And the more porn users who reported experiencing stalking, harassment, or abuse, the more likely they were to seek help.
And although porn users have been shown to be less likely in the workplace than their male counterparts, they are still far more likely in relationships than those who don’t watch the games.
“If we can reduce these rates of pornography use in our population, we can also increase the number and type of partners,” Ley said.
The researchers also found some troubling results in a study of college students.
When asked about their sex lives in the context of a hypothetical “game” with a woman, the students who had played the game were more willing to have sex with a male than a female.
But that change wasn’t found among the students that hadn’t played the video game, and when the students were compared to other college students, the changes were more limited.
“The study is a
