Is it normal for people to not cheat in relationship?

It's because people who are in a long term relationship is connected physically and emotionally. They find other things, ie communicating or bonding activities, just as stimulating as pounding each other's sexmakers. It's called love.
That feeling that makes people grow on each other. Like warts. Or a fungal infection.

I've never cheated.

I know some married men still have strong sexual desire whereas the woman has long since retired.
One guy told me that if you were to put a marble in a jar for all the times you have sex in your first year of marriage, you would fill the jar to the brim. After that first year, if you were to begin to remove a marble every time you had sex with your wife you would die before it was empty. Hahahahaha

I've cheated and been cheated on. My girlfriend now though, for some reason, has me whipped. I will look at other women but I won't touch because sure enough, her crying face will pop into my mind and I wouldn't be able to do it. I think it varies with each individual's conscience and who they'te with.

Fuck if i know.

What i do know is that i have up to now never cheated on my wife.

I say up to now because who knows what the future may bring i hope i do the right thing if the opportunity drops on my lap so to speak.

But as we are all human i can't say for sure.

I can't imagine cheating. I just couldn't hurt him like that. I can understand that either of us could be attracted to other people, but does it really take that much self control to not cheat?

I just can't understand it for myself. I have friends who have cheated, and in their circumstances, I see why they did it, and I don't judge them, but I still don't condone it.

You're deluding yourself if you think you will never be attracted to someone else in a ltr, nor have the urge to cheat. And I suspect that that delusion greatly contributes to people actually cheating because they're caught off guard and unprepared when those urges inevitably pop up.

I think it's a difference in lifestyle and mentality? Some people live life pursuing anything and everything that gives them pleasure. For others, pleasure exists in making difficult/meaningful/moralistic choices.
