Let's Find Out

My neighbour who lives at the rear of my property, watches me wank most evenings.
He pretends he's not looking but a few days ago I caught him whacking one off while watching me.
I'm reasonably well endowed with a very high libido, but have never been with a guy sexually.
He's in his late teens early twenties I think. And from what I've discovered recently, a young gay man.
This coming weekend I'm going to put a large piece of paper on my window with my phone number on it, and an invite to call round.
I think it's time to find out if Id like fucking a guy. He's certainly good looking enough.
