He's flaccid though, lol!! Flaccid length is not a good indicator of "happy showtime" length. We all drool over Andy's flaccid "ding-ding", but for all we know it may barely grow from that length.
White guys generally seem to be growers though. If Muz is a grower, ouch!
Even if he's kind of a shower, it'd still grow probably 2-3 more inches and still be a damn good size.
