On a woman... I would have to say.... tits  
On a guy I would have to say....the balls

Men: I love a handsome face, especially a sexy smile. Another body part that catches my eye in specific is when men where casual shorts or sweats and you can see the print. Wow!

That crease right where the bottom of the butt cheek meets the top of their legs

On a woman, I tend to gravitate towards her rear end so I guess you could say that I'm an ass man.  The curve between her back and ass is also quite nice, especially if she has those dimples on both sides.  I also love women with cute faces and sexy eyes.

Yes her brain is important, I'll give you that but her most important??? You aren't a visual guy? So if a young lady who can recite "War and Peace" is butt ugly, that's ok??
Hey, but whatever floats your boat.

is  his arm, specifically his bicep, especially watching it get tight and pumped while I'm on my back beneath him.  
So hot!

On a man ~~ the V-line !  
On a Women ~~ a nice round butt and a smile!

On a man, his smile.
On a woman, her lips. I love naturally full lips.
