I love his cute, soft, hairy butt in the morning when he's shaving.
I love the way he looks in a towel fresh from the shower.
I love the way he gets little-kid-excited about things and jumps around... nekkid.
I love how, after a few weeks of frustration and emotional distance, he makes it a point to remind me that I'm important and that it didn't revolve around me.
I love how he pokes me in the head at night (gently) when I'm on his side of the bed, but plays the part of hibernating grizzly bear when he's on my side.
I love the way he gets completely sucked into World of Warcraft for hours, but will still answer my questions about it or talk to me even though it's screwing up his game.
