When gazing at a cock, what grabs your attention first: the size and shape of his head, length and/or thickness of his shaft, or shape of his balls?
The person it is attached to.
What its owner looks like of course
I agree with Nikki and Genelyn. Cock is nice but I am more interested in the whole person. I will take a closer look at the cock as it enters my mouth!
My attention goes to the obvious first - pretty much the overview of what you're seeing.
1. Circumcised or not (I always assume cut but I'm aware there can be surprises)
2. Size (thickness, length)
3. Pubes (shaved? trimmed? dreadlocks?)
4. Balls (size + smoothness)
Then once you've taken in the basics, you can appreciate the finer points, like:
1. Dick Veining
2. Skin tone/colour variations of dick 'n balls
3. Shape of head
4. Straight or curved
5. Ball details
The smile. The genuine joy of being with me, the sense of mischief.
Maybe later might look at the "little brain"....
I don't really care what it looks like, so long as he knows how to use it.
How hard it is, or more accurately, whether it's ready to go or not!
