But, while straying is usually blamed on being a ‘mistake’, often thanks to ‘being wasted’ – new studies have revealed that it could actually be down to genetics and biology.
It’s time to get our science hats on for a minute.
Hopefully you’re all aware of the hormone Dopamine, which is released after we participate in pleasurable experiences – such as eating or orgasming.
But what you probably didn’t know is that the type of Dopamine we all have varies.
This is due to varying lengths of Alleles in individual's DNA.
According to the study, 50 per cent of people who have the Long Allele variation have cheated.
In contrast, only 22 per cent of people who have the Short Allele have played away.
So essentially there is some truth in the old saying ‘once a cheater, always a cheater’.
Another hormone we all have is Vasopressin, which controls our trust, empathy and social bonding.
Former studies have shown that lower levels of Vasopressin can influence cheating.
But, of course, life factors do play a part. Men who earn more than their female partners, and stay-at-home dads, are much more likely to play away from home.
It’s thought that when both parties have the same earning potential, the chances of cheating on each side are slashed.
And not forgetting past events, such as a bad break-up, which can also impact a person’s ability to remain monogamous.
Unfortunately not enough research into same sex couples has been completed to gain an insight into their cheating habits – but this study certainly suggests that a lot of it is down to what we’re made up of.
