When it comes to being sexually promiscuous, it seems that no one makes the cut quite like people who are socially dominant, very friendly or very aggressive.
As to why these three categories of people are more likely to sleep around, well according to a study it seems that while warm, friendly people like sharing their joy with others by hopping into bed with them, aggressive people do so to keep a monogamous relationship at bay, while having a dominant personality just makes it easier to approach people.
The study was carried out by Patrick Markey, a psychologist at Villanova University, and his wife Charlotte Markey, a psychologist at Rutgers University. They asked 210 adults to take a test to measure their interpersonal characteristics, as well as indicate with how many people they had engaged in certain sexual activities.
On comparing the responses the researchers found that while dominant people, keeping with earlier studies, were more likely to be promiscuous, the same was true for people who are either very friendly or very unfriendly.
They also noted that people who are just moderately friendly are the least likely to sleep around.
As for why friendly people sleep around since promiscuity is regarded as a moral failing, well Patrick Markey thinks that it may have less to do with pleasure, and more to do with spreading friendly feelings.
It could be that someone is not doing it to achieve the most pleasure. Someone actually might be doing it as an expression of their warmth to other people, LiveScience quoted him, as saying.
A warm person might hug lots of people or might kiss lots of people. Well, maybe a warm person might sleep with lots of people, he added.
The study is to be published in the Journal of Research in Personality.
