I tend to look at the entire package, though there are always exceptions...
some of my faves...
Jake Andrews... what a body... no gag reflex, and LOVES to be bad
Carlos Morales... the consummate sex pig. Hot as hell whether topping or bottoming.
Cliff Parker- dark, sexy eyes... hot as hell whether hairy or smooth. Nice cock, incredible ass (an all-day sucker/licker)
Eric Hanson- gorgeous face, awesome body, ass, & cock- even bottoms on occasion
Johnny Hanson- great body & a beercan cock- too bad he never sucked cock or bottomed.
Mike Branson's in there as well... though could never understand why he'd never suck cock, but he'd rim like there's no tomorrow (gag reflex, maybe?).
Mike Henson was a nice total package, as was Bill Henson.
John Davenport- god, what a beautifully smooth, toned body to go with that drool-worthy cock & ass.
For me, one of the most perfect examples of a gorgeously hot masculine/male physique would be Francois Papillion. He only did a few movies, rarely letting a guy touch him, but what a beauty.
As far as the newer crop of porn stars, gotta go with Josh Weston & Brad Patton. Josh's unbelievably ripped body, combined with that lily white skin make him look like he was carved out of marble. Patton's got an awesome cock (and body), though the fake bake/spray-on tan always seems to be overdone.
Early- Ryker was hot, though he never seemed to be able to do much with that hog between his legs. Chad Hunt's definitely got the more "serviceable" monster cock. He's cute, though the ink work is a bit much for me.
I could go on & on, so will stop there for now.
