Men and power vs. biological instincts

People have been asking this question since the dawn of man "Why would a man risk everything - his reputation, his family, his freedom - for a few seconds of sexual exploitation" as is expressed in this "For Better Or For Worse" comic strip at http://www.fborfw.com/strip_fix/archives/002159.php The relevant portion of which is reproduced below.

The reason is the same as why a male praying mantis engages in mating, in spite of knowing that his head is going to be chewed off by the female during the act.

Obviously, it isn't an instant gratification issue; it is ingrained in our biology. Maybe, this is explained by the theory that biologically, we want to propagate our genes. So, we look for all opportunities to increase chances -- even if it means dying himself, as in the case of praying mantis, or losing everything we have, in the case of some humans. Or, attempting to fight the alpha male - as is the case of many mammals.

If it is biological, why do more men not do it? Because the human society has created rules. So, the question that is to be asked is - why is it that some people are able to follow rules, and keep their biological instincts under check.

So, it isn't power, as the comic strip seems to imply. It is the lack of power over biological instincts that is driving this behavior.
