I have to begin with urban dictionary explanation:
The male human when erect is one of two sizes. Long or rather short. Most males grow to an extended length after a rush of blood enters the penis. This person is a GROWER.
Some males will not grow in length when peaking an erection. These males are as long as they are gonna get, either stiff, or soft like a bunny. They are known as SHOWERS, as they show their goods in the beginning.
What about Rocco?
First of all he’s very exotic looking he might also have some Arabic genes and needles to say he is a real turn on for me. But his cock seemed rather small when he took off his pants but you can see that it grew well beyond average and that made his solo video more interesting 🙂
By “Side by side comparison” he is larger 4 times when erected. So we can conclude he is a true GROWER!
