that looks really good.

I think Jacob from seancody, and look throught the guy site, there are a couple guys who have a small dick (big muscle jay, brendan the musclegod, zack, etc.)

Not really a bad height for bodybuilding at all. There are less bodybuilders who are tall. I would say on average it would be around 5'8 but higher or below that a bit should not be a problem at all.
