Even if they love their partners, most men will always end up cheating just to have more sex on their side, an American sociologist has claimed.

According to the study, men who do not cheat are setting themselves up for ‘socially-compelled sexual incarceration’ however, men who cheat, enjoy best of both worlds.

Eric Anderson, who teaches at the University of Winchester in England, has asserted that monogamy has ostracised men from doing what they most want to do, the Daily Mail reported.

In his new book The Monogamy Gap: Men, Love, and the Reality of Cheating, Anderson has mentioned that cheating is the norm, not the exception to it, and it is high time that people begin embracing ‘sexually open relationships that coexist without hierarchy or hegemony.’

The study, which surveyed 120 undergraduate men – both gay and straight, revealed that 78 per cent of those with partners cheated, ‘even though they said that they loved and intended to stay with their partner.’

In an interview with the Huffington Post, Anderson said that men want to be emotionally monogamous, though their ‘body craves sex with other people somatically.’

“Our physical desires don’t die; they just change from our partner to other people…When the sex dies, the relationship has just begun,” he said.
