The Georgie Boy I have in my mind's eye is more like Buddy.
or Daffyd Thomas the Only Gay in the Village
Buddy and Daffyd, two really funny gay characters.
What makes Buddy and Daffyd funny isn't that they are gay, it is the self centered nature of their view.
Buddy think he's hot shit.
Daffyd is a small town gay that has clung to the identity of being the only gay because it makes him heroic in his own mind. It is this heroism (in his mind) that means he must stay in the small town rather than take risks and move somewhere where his life would probably have more meaning. This heroic act is actually his own fear at work. That's subtle, yet the laughs that come from the audience aren't subtle, they are full on belly laughs.
As somebody else in this thread said, make Georgie-Boy more than a character, make him human. You might start by giving him a respectable name that a real human being would have. (George)
