Biologically speaking men are in the middle ground.
There are male mammals that are polygamous such as chimpanzees etc and there are male mammals such as gorillas that are by nature monogamous...
Human males fall in the middle statistically.. by that i mean it is WORK to stay committed, but it is very much possible.
Monogamous commitment for men and women is much like sticking to a financial budget, a healthy diet, or following the rules of the road when driving your automobile...
It sucks, and it is work, but its do-able.
The payoff is the same - long term you get stable finances, fitness, and a clean driving record...
Most people can't stick to their commitments, that's all it really takes is staying power.
