Yes, I love when I see a guy I know (friend, co-worker, acquaintance, etc.) naked for the first time, e.g. in a locker room, shared hotel room, etc. Obviously, if he's hot, there's the visual pleasure aspect, but regardless, there's the bonding aspect upon learning that he shares my belief that in such appropriate settings, men don't need to be modest about other men seeing their dicks. If I'm not already naked or haven't been naked around the guy before, I like to do so (either at the time if it fits the timing, or a later point) to complete the bond.
