Is it unusual to feel this close and affectionate with my friends?

Where male or female, all walks of life, you unconditionally love and appreciate each other and tolerate everyone's faults? I was wondering if it's unusual to be as close to one of my best guy friends in particular as I am. We hug and kiss each other on the cheek when we greet and say goodbye to each other, but there's no attraction on either side and I share my food off my plate with about two of my guy friends and share my bottle of drink with one of my girlfriends that I'm really close to.
