Have a promiscuity problem? Can’t quit cheating on your partner? A new study suggests that the problem may be in your genes, rather than your jeans.

In the study, reported Nov. 30 in the online open-access journal PloS One, researchers asked 181 young adults about their relationships and sexual behavior, including how many people they’d slept with and how long they knew their partners before getting down and dirty. Researchers also gathered DNA samples from participants’ cheeks and tested the samples for DRD4, a gene that has been linked to thrill seeking behaviors like drinking and gambling, as well as a love of horror movies and liberalism. The results?

"What we found was that individuals with a certain variant of the DRD4 gene were more likely to have a history of uncommitted sex, including one-night stands and acts of infidelity,” said Justin Garcia, researcher and doctoral fellow at the Binghamton University in New York.

It seems that half the people with the risk-loving DRD4 gene had committed infidelity in the past, as compared to 22% of the people without it. I guess the men and women on Cheaters weren’t lying when they said they couldn’t help fooling around.    

However, couldn’t immaturity be to blame for a lot of this sexual behavior? It’s a lot easier to cheat on someone or sleep around when you aren’t married or in a committed relationship, which is the situation of a lot of young adults. Plus, young people are just hornier than their elders! What do you think?
