They had what, 2 kids in their first 5 years of marriage?
that's a lot of time for tiger - virginboy who suddenly got himself a supermodel - to suffer from some serious blueballs. She probably taught him to have sex (and he hated condoms with his hookers, so you know he never had much of a sex life before her).
So he finally discovers sex, realizes "I'm worth a billion bucks and there are dirtballs in bars getting more new ass than me". On top of it, the wifey spits out 2 babies - and all the dads here know how much it sucks not getting laid while the wife is 7,8,9 months preggo, then afterwards.
Tiger has women throwing themselves at him. He has hotel rooms and women promising to keep it their little secret. So one day, he cracks. Then, at that point, he's aware he'll get caught eventually, so he figures he'd better screw a hundre of them to get his money's worth.
And it's not that bad for Tiger... What can you really buy for a billion dollars that you can't do with $100 million? He has the freedom now to hit as much new tail as he'd like. The only sad part is he won't see his kids as much.
Lesson to learn? NEVER GET MARRIED
