Private Practice, Season 3

Cooper:
[to a patient who doesn't want treatment] Well, I admit I don't know what it's like to get old. But when it comes to sex, I get that. And when you can't do it, I mean that is... Look, it happens, and it happens to every guy. I was with a woman I loved and we're fighting a lot, and, uh, I... I was stressed out and it made it difficult to perform.

Schmidt:
And it was humiliating?

Cooper:
Oh, it was. And so I pushed her away, and I treated her badly because I was feeling like I was less of a man. I was, I was wrong. I was wrong. Mr. Schmidt, I can't promise you that there'll be no side effects if you do this treatment, but I do know that you'll be alive. And you will get to continue to love Nora for a long time to come. You will be the man in her life, and that's the most important thing.
