Just thought of our partner being with someone else, is causing us nausea.
However this feeling may differ between women and men.
New study by US - Chapman University in California reveals that there are other things that enrage men, when it comes to infidelity and other are those that hurt women.
From the findings, American researchers showed that men get angry at the thought that their partner keeps an affair with another man, while women are hurt deeply from the emotional bonding that may have developed between their partner and another woman.
•Sex without emotion or love without sex?
Within the study the experts asked 64,000 people to declare what it is that will hurt the most:
i. Finding out that their partner maintained a love affair with a third person, without being in love with ?
or
ii. Finding out that their other half is in love with someone else, but has NOT progressed to sexual intercourse ?

● 54% of men - compared to 34% of women - said they would hurt more from the sexual infidelity of their partner rather than an emotional attachment to someone else . Although there were identified differences in the views of the volunteers, based on their age group, their social status, income levels and their history related to infidelity, the researchers found that gay men expressed views closest to those of the women.

Erotic jealousy with evolutionary background
As the researchers report in their publication in the journal «Archives of Sexual Behaviour», the attitude of men towards sexual infidelity may hide an evolutionary dimension rooted in their paternal uncertainty. For example, if a man is in a relationship with a woman, finds out that his partner is pregnant and does not proceed to a paternity test , he can not know with certainty that the child is his.
"While one would expect, that both men and women, manifest the same levels of jealousy, men may have much stronger reactions than women," scientists say.
"On the other hand, women do not face the fear of maternal uncertainty, but they face the fear, of the risking to lose the loyalty and support of their partner if their partner had to turn his interest to another woman.“
"If a man discovers that his wife has a love affair with someone else, it triggers his masculinity.
This could lead to a more negative reaction on hearing of a sexual affair, than finding out an emotional bond that does not involve sexual intercourse "experts underline.
"Women grow up with more emphasis on the emotional side, they think more of the longevity of the relationship and they become emotional nannies within it. This means it can hurt them, a lot more if they find out, that their partner is in love with another woman than if they find out that he cheated once, without this to mean anything more serious and deep for him.
