Every successful person will tell you that Groupies and Bonking are part of the price of fame. It is not about his Wife; it is about the frailty of succumbng to the pressures that others put on great performers. Not many can avoid it. His wife knew that when she married him.
The critics are not important and are by the nature of a critic enjoying celebrity status within their bloodlust.

Tiger Woods is human afterall. He was great before he met his wife, during and will be afterwards. Leave the guy alone; he is what most of us dream we could be: a champion.

At least that way he can enjoy his romps. Maybe he could give a few sex tips as well as golf tips. He seems to have plenty of experience in both fields.
