Who and When?

Timing is important when it comes to whether someone chooses to cheat; it can also determine with whom they’ll have an affair. Let’s see how!

#11 People that are economically dependent on their spouses are more likely to have affairs


Someone completely dependent on their spouse for financial support is more likely to be unfaithful; this especially true for men that earn less than their partner. However, if men earn significantly more, they are also more likely to cheat. If you were wondering why people cheat, here’s one big indicator.

#12 The most popular day to cheat is Wednesday

Why and With Whom?

Now that we’ve discussed what percentage of people cheat, let’s discuss why and with whom. Many factors influence cheating; contrary to popular belief, lack of love, sexual desire, compatibility, or being unhappy in a relationship are not the most common reasons for unfaithfulness. Time to look at the facts!

#15 Genetics may influence whether you cheat


Genes may influence the likelihood of cheating! Oxytocin and vasopressin receptors can vary in each person and may determine how many women cheat as well as men. People with less sensitive receptors are more likely to cheat, as they experience less empathy and trust. 

#16 Women that communicate more with their partners are faithful

(Investigation Hotline)

Faithful women spend more time talking to their partner. When a woman is committed, she may spend 30 to 60 minutes per day talking to her partner, or more. Facts about cheating girlfriends reveal that they spend 5 minutes (or less) seriously speaking to their significant other. If your woman isn’t talking to you, it might be time to face your problems

#17 Females are more likely to cheat due to emotional reasons

Things You May Want to Know

Before we reach the end, here are a few more interesting facts about cheating you may want to remember.

#21 Cheating increases the risk of STDs


When we look at how many people cheat, it’s obvious that cheating is harmful, especially for the sexual health of everyone involved. Most people in committed relationships don’t use condoms, and when people cheat, they don’t use protection either. This leads to sexually transmitted diseases spreading, which is often considered the ultimate betrayal

#22 ‘Once a cheater, always a cheater’ is true

(Sex & Psychology)

Research confirms that people that have been unfaithful before are likely to stray again – three-and-a-half times more to be exact! The percentage of people who cheat is higher among repeat offenders, so if you’re aware that your partner has previously been in an unfaithful relationship, be wary. 

#23 A small percentage of relationships still last after an affair

When we look at how many people have affairs, the data is obviously concerning. Luckily, there’s a way to prevent your significant other from cheating – cuddle with them! Vasopressin, or the cuddle hormone, helps people form a bond; the stronger the bond, the less likely they cheat. People with low vasopressin levels reported higher levels of dissatisfaction in relationships and lower levels of trust.

#27 Men can produce ‘paranoid sperm’

(Amy North)

If a man suspects that his significant other may be cheating, his body can produce paranoid sperm. This refers to the body producing more ‘fighter sperm’ to stop anyone from inseminating their partner.
