I'd have to say the only time I'm not thinking about boobs is when I'm thinking about the beautiful women that get to have these wonderful gifts. Big and small I love 'um all. Of course my favorite kind of boobs are "friendly boobs" that like to be shared with me. I swear, if I had a set of my own I'd be playing with and looking at them constantly. Nothing compares to the feel of a nice pair of boobs gliding gently across my body. "BE ON THE LOOKOUT! THESE THINGS USUALLY TRAVEL IN PAIRS"
This is my theory: Most guys only think about boobs ONCE in their life, and that ONE THOUGHT continues until they die. Meaning we ALWAYS think about boobs.
