This guy has really got it wrong. Or he might have it right for himself, but he’s not representative of the larger population. Just googling for any scientific studies of male infidelity will show that it’s not about sex.

I’m not the cheating type, but I know when I’ve walked out on a beautiful woman.

If your girl appreciates you and you feel it, nothing can get you down. Shitty day at work? Your career ambition keeps getting harder? If you’ve got a girl who makes you feel like you will do it and she’s by your side, why would you look anywhere else?

As opposed to “Honey, what did I tell you about leaving wet towels here? Didn’t we agree that they are meant to be in the hamper?” and always questioning your abilities. No wonder when you meet that girl in accounts who looks at you like she knows your real worth, no wonder she looks gorgeous.

Only 8 per cent of the men said that sexual dissatisfaction at home was a primary contributor. The No. 1 answer, 48 per cent, was emotional dissatisfaction at home. And that fit with another amazing statistic: 88 per cent of the men said the mistress was no better-looking or was not in better shape than their own wives. It’s not about sex. It’s much more about a lack of thoughtful gestures at home.
