Monkeyleg, First off, I agree with the others who've already said you need to find another doc because, IMO, this one sounds like moneygrubber. Sounds to me like he's paying more attention to the stopwatch than he is to the patient. It also sounds like he's trying to convert his patients over to his own leftism and that's unprofessional. And like Bogie just said about the one hour a year can't be doing all that much. You'd get more time leaning on the gun shop counter or talking to the bartender at slack times.
Your father may have some experience or insight you don't know about. You won't know until you bring whatever it is up. But, if it's too personal for the parent/child relationship as we know it as adults, then I'll agree that it may not be comfortable.
Someone asked why it can't be your wife that you talk to... sounds reasonable. One reason I've understood men and women get married would be emotional support and sometimes one can see things the other can't.
Your friend who had sexual fantasies about your wife... I don't know, but he may have needed to talk to somebody about that out of guilt. If you and he have been friends/confidantes for 41+ years, he may have felt you were the one he could talk to, or had to talk to. I forgot where I read this, but psychologists have said if someone has dreams or fantasies about a friend's wife or an in-law or someone, the one in the dream or fantasy is a stand-in for somebody else. So that may be nothing to worry about, especially if you really trust your wife and she really is what she should be. But I can see why your not comfortable; goes back to a man wants to be the only one who wants to be with his wife. It could be envy, too, and you might also take the combination of envy and honesty as a compliment to you, your wife, and your friendship with this guy.
Your father and your wife are closest to you. I'd think try them first. Those two relations... I don't think they'd normally sell you out. Even if you're not particularly religious, preachers can be a good source. You just don't want to wind up with one who thinks he's holier than thou, IMO/BT.
I hope this helps.
