Do you have a link to that? Maybe for some men. Nearly every case I have seen(including mine) it was between friends and coworkers.
Women don't normally have one night stands with strangers when they are married. Women have affairs because of their perceived lack of love and affection they are not getting from their husband which leads them to having an affair. Most women need an emotional basis with the man to have sex with him...not all cases but generally.
Men are the complete opposite..we don't need an emotional connection or have to feel love with the woman-might not even like her...we just want the physical release.
I’ve never bought into the whole women are one way men are the other thing. Largely because it doesn’t make statistical sense. If women mostly need to bond with a man for sex and men are mostly into one night stands well who are they having sex with? Clearly a significant portion of one side is willing to do things the same way the other side does.
Don’t know where I saw that the real danger was the stranger run, one of those articles that floats around. It makes sense if you think about it. For one thing the person being cheated on will always be more suspicious of the spouse’s friends, which makes them a bad target right away. Plus the situation is too internal then, walking away is more sticky when they can turn you in. Strangers are safer, and they have the air of mystery and spontaneity, two things that are very attractive and hard to keep going in an ongoing relationship. Of course as always remember for something to be the most frequent case it only has to happen more often than the other, not necessarily the vast majority of the time. If it’s strangers 35% of the time, and friends 32.5% of the time and co-workers 32.5% of the time that makes it strangers most often.
