1) Their hair, especially when it looks styled but isnt.
2) Hugs. The gods know I love hugs.
3) The way they think. Girls and guys think differently when it comes to solving problems, and as much as I hate to admit, sometimes they think of intelligent solutions that I would never have thought of.
4) Their hands
5) Nice eyes that show a bit of mischeif
6) I like it when they have a toned body and look strong, but do not have huge scary muscles...
7) They can look formidable even when they don't try.

You can sit in companiable silence. Girls talk into their voices are nothing more than a buzz in your ear.
9) They have great oversized (on girls) hoodies that they let you borrow that has their masculine scent
10) They can be the sweetest, most adorable, protective things in the world, or they can be complete jerks. I dont know why I like that... But its sexy.
