Being faithful and monogamous is not natural for human beings. It takes work. Deep down we all know that. We have all been tempted to stray at some point or another. Even when it was only a fleeting thought and we didn't act on it. Every time we acknowledge that someone of the opposite sex is attractive or sexy we are doing nothing other than pointing out that they would be a suitable mate. Not acting on that natural impulse to want to mate with a viable mating partner requires a conscious decision. It's a constant struggle between what your body wants, and what the civilized part of your brain says you should do, in order to avoid the negative consequences of cheating on your spouse and ruining your long-term relationship. That's why affairs, and extra-marital sex, are often referred to as a moment of weakness.

It's probably not easy for a woman to understand what it's like to be a man. Imagine you're starving, and someone puts a huge buffet in front of you. There's delicious, mouth-watering food all around you, and it's really really hard not to eat it all. That's what it's like to be a man around attractive women. The urge to want to hump everything that moves is part of a man's natural programming. It's a deep-seated hunger. To suppress that hunger takes civilization and a lot of willpower.

Men know that most women want to have an emotional connection with someone before they sleep with them. Men know that a lot of women think it's romantic to be friends first, and then the friendship blossoms into a relationship. Men know that they have to jump through all these hoops first, before they can get laid. And that's really all romance and courtship is to a man: hoops he has to jump through to get laid.

When guys try to get a good job and make a lot of money, it's so that they can find a good mate, because they know women like guys with money. Big tits are to men, what big wallets are to women. A sexy woman can have almost any man she wants. And a rich guy can have almost any woman he wants.
