How can someone actively hate themselves so much that they actually crusade against their own self interests?
Well, how do you know what's against his own self interests? He's got money - enough to travel to Europe and hire a (alleged) gigolo as a companion for the trip. He's respected in his own circles. Sure he can't live as an "out" gay man but maybe for him that's in his own interests and living as an out gay man holds no interest for him. He may actually get off on the "perverted" nature of his lifestyle and resent attempts to make it normal rather than a perversion he indulges himself in.
You never know - humans are strange beasts.
