Is why do men look for sexual gratification outside of their primary relationship genetic?
Historically we came from a tribal culture of numerous women per male as hunting was so dangerous the balance of males to females would have been lopsided. Then there is the need of men every three days but for women it's a few days per lunar cycle so a ratio of 2 - 4 females per male was not unlikely and there is genetic evidence that 8000 years ago it was more like 10-17 females per male. It's only been in the last few hundred years that monogamy has become the law.

@ErecSchunn Perhaps..but are infidelity; as well as marriage, just constructs? It would appear that humans are not designed for monogamy. Otherwise why would females have multiplse orgasms while men just fall asleep? Meanwhile, we now appear to be falling towards no marriages and very few children. As religion looses its' grip, reality steps in like a three year old to ask "why?".
