Natalia: Most men are weak when it comes to a pretty face and a promise of hot sex. Based on the numerous comments on my first article, I think a few women are in denial.
I have brothers and several male friends from very different backgrounds that confide in me about their marriages. They all have one thing in common -- they're always looking for "NEW" unfamiliar territory to explore. This isn't a reflection on their wives, because most of the ladies are great partners. These are regular guys: teachers, bank tellers, retail salesmen, etc. Several comments insist that "money" is my motivation. That is so far from the truth. A man's income has nothing to do with him being unfaithful. We just hear more about "high-profile" celebrities cheating through the media.
Here's the bottom line ... most men need physical stimulation, they desire a partner that is visually pleasing to their eye and is willing to have sex. In my opinion, THAT'S JUST HOW THEY'RE WIRED! However, that doesn't give them an excuse to stray; they still have to be responsible and "just say no" to temptation.
Marriage is full of peaks and valleys, but it's a lot smoother when couples are honest and realistic.
