Wow, perhaps the sexiest picture I've ever seen of him. The way he's gripping the stool with his big hands with some well detailed veins, the bare muscled arms, the loose sweeter vest with no shirt so you see some chest hair poking out, his pants being tight enough to have all those folds in them like many arrows just pointing straight to his crotch, the necklace accentuating his thick muscled neck, the very open/questioning almost lightly cruisy look he's giving the camera, his lips slightly parted.
Each individual thing is subtle, but it all comes together to evoke quite the theme here, there are so many different things all hinting at if not a desire, then at least the ability to give you a good time. Whatever photographer took this is did a great job if all those choices were intentional.
