I don't get this.
You're married to a Playboy Playmate who still has it after having had kids.
Not that if your not married to a Playmate it makes it alright, just saying. WTF?!
It goes to prove that a great many men will cheat no matter what their wife does, how she behaves, or what she looks like. A lot of men are just cheaters by nature. She had little kids, which presumably took a lot of her time and energy. He's selfish, felt neglected because he's not a grownup, and felt entitled to pussy on the side. It's a very common story. Same with Tiger. He has these voracious sexual appetites, needs sex 24/7, and his pretty wife is an ordinary human whose attention (rightfully) was going to her small children so he didn't get it whenever he wanted--not that it would have mattered if he had. Tiger would have cheated no matter what she did. A lot of men are compulsive womanizers. That's a "sex addict" when you remove the pathology and acknowledge that their only "illness" is that they're supremely selfish.
