Quite a few guitarists treat their guitar like a lover. When you play the guitar, you hold it tight. It's portable, and you can go anywhere with it. That's how it differs from a piano, which I learned as a child.

According to a friend of mine, one guitarist said he was turned on when someone else played his guitar because he felt as if his guitar cheated on him. It was foolish and funny, but I kind of got him.
