What is the psychology behind female finding her lover being disloyal?

One obvious point is they get upset and mad. Sometimes it even gets to the extreme that they want to leave the guy.

However, let us limit this question to the psychology behind a female lover who catches him looking at porn. All guys look at porn, but the psychology works differently when she catches you doing it secretly. So how will such woman feel? Deep down inside the woman, does she actually get turn on by this ?

Of course this all depends on the type of woman we are talking about. The more sexual,playful and confident one wouldn't mind.

But let say the woman is not very secure. Would she still get turn on? Turn on as in "I shall please him instead of those porn" , or is her psychology 100% being angry at you?

Just wondering. Hope this doesn't sound like a stupid question.

Thanks in advance !

I only know this generally as its been a while since ive studied this
But what i can remeber is its to do with evolution and psychology
I will give you a brief introduction (so you understand what im talking about before giving the answer)

Women thousands of years ago would get pregnant guy would leave and she would have to find her own food which lowers chance of survival of baby and her

The guy would leave because hes unsure if other guys have slept with that woman and he doesnt want to bring his resources to her and the baby which might not be his

Woman decided to sleep with only one man continuously to get his resources , And the emotion of jealousy evolved both in men and and in women

With women only sleeping with one man . Man felt comfortable enough to gather reources and bring woman and child food . However if he saw another man by his woman he would get jealous and attack him to prevent confusion about whos baby it is .

Woman would get jealous if Man shared his resources with other Women.

Bringing this into modern life and to get to your answer Women are more botherd if a man gives a girl money , presents , holidays ect because theese are resources She is less likely to be botherd if a man is sleeping with another women if he isnt giving her any resources at all ................strange i know
If you are looking at porn she may get jealous but she knows that you cannot share your reources with some video on the internet so im very doubtfull that she will give you more sex for looking at porn on the web :\

What? Jealous for looking at porn? Haha! Dude my ex's would put the porn on for me while giving me a blow job! Sex her right and become an awesome lover and chicks will do almost anything for you regardless of how secure they are. Trust me! You have to make them feel comfortable and sexual. But finding me with another woman I'm sure they would not have appreciated.

Dude my ex's would put the porn on for me while giving me a blow job!

Now that is a man that has his sh*t together.

Well, not exactly jealous for you looking at porn. Maybe, the girl would feel a little betrayed because you are looking at other girls' body?

I don't really know exactly, so that is why I ask this question.

"Woman are so hard to understand" They get angry sometimes for stuff that you think they wouldn't get angry for, and it makes you wonder why.

If a girl feels betrayed (or jealous) because you are looking at porn, dump her...she is a basket case and will cause you nothing but grief. An open-minded, level head, fun girl could care less if you are looking at porn. In fact, she will sit with you and watch it, or pick out something for you 'both' to watch.
