His mojo got ruined as soon as the sex was no longer illicit. For him, it was all about the "I'M TIGER FUCKING WOODS and I can buy whatever, and can do whatever, whenever, to whomever I want, bitch!" When the risk of getting busted was gone, it fucked wtih his head. I bet he has not been laid - or has not gotten all the way to happy land - since the sex clinic. Would not be surprised if he was unable to get a stiffy right now.
