It's all about the face and the physique. Before I even want to look at a person's bulge, I would rather look at their face (especially the eyes), their hair (or lack thereof) and body type. I tend to go for more down to earth looking guys than the fantasy types. Ones that look more mature and manly than boyish and twinky. The ones that would rather watch football on TV than Desperate Housewives, but aren't afraid to let their hair down when the time calls for it. And I love neatly groomed facial hair. Moustaches, goatees and some beards are a weakness for me.
Basically, if you look like OCMuscleJock and gave me a playful, but devilish smile I'd drool. :biggrin:
But even if you didn't have his physique, I'd probably try to give you some eye contact.
