While infidelity is often blamed on sex addiction or commitment phobia, a new study reveals that sexual insecurities are often the reason someone cheats.

Researchers from the University of Indiana surveyed 506 monogamous men and 416 monogamous women about their sexual behaviors and the quality of their relationships. They were also asked whether or not they'd cheated on their significant others.

Twenty-three percent of the men and 19 percent of the women admitted to participating in a sexual act with someone else that could potentially ruin their current relationships.

The team also found that women who worry about staying aroused and actually reaching orgasm were 8 percent more likely to cheat while men were 6 percent more likely to cheat if they are insecure about impotence and premature ejaculation.

"People who score high on sexual anxiety may feel less pressure when they're engaging with a person who doesn't know their sexual history," lead research Kristen Mark told the Daily Mail.

The findings also showed that those who cheated "were half as likely to be religious" and employed.
