Of course size matters. One can make up for lacking size with supreme skill, but increased will almost always add to the experience.

Kevin Bacon's was impressive in Wild Things. But honestly, scrawny guys usually have nice ones. Whenever I see a tall scrawny guy I assume he's packin' .

Still, it's hard (ha) to tell when in most of the movies the guys aren't erect. They could be growers, not showers. I thought Michael Fassbender had a good-sized one in Shame. It was only around semi-erect too.

kevin bacon was not packing in wild things. Its not small but its not big at all

It was very good sized. My cousin watched it with her girlfriends and they were shocked he was that big .
