Definately BS, I am 42 and have been Married with children to 2 different women who both cheated on me. We had sex often, 4 plus times a week. Made good money, new house, new car etc.
No excuses for them other than they took the bate when friends got in their ear about "Girls Night out", and crap like that.
Both ended with crappy lives as they found that they repeated this behavior with others. I have no desire to be with a woman again. Years of child support and starting your life over sucks.
This guys study as so many of you pointed out is using the wrong group of "BOYS" to make his case.
Real men work hard for their families and work hard to keep them together.
