Be yourself Sheldon.
Personally I'd say make the contact because it's not a chance that will happen for much longer and you never know what you will look back on and regret not happening.

Just accept that this is a man who shares your genes and nothing else.
Like if a genealogy search turned up a third cousin twice removed (no, I don't understand that either, I think it's only important in landed titles). You'd want to meet them out of curiosity at least.
This man is not a father to you. And he obviously isn't trying to be now.
You were a spurt of sperm as far as he was concerned.
But you were born, you grew up and you became your own man. I have no idea what you are like IRL, but on the Cellar you are special, witty, cutting and enormously generous.

That man lost out. Never mind.
Just don't lose out yourself.
If you really don't think you will miss out, have nothing to do with him. You succeeded already.
