Hi, penis owner, the penis does, in fact, grow when it becomes erect.
"In general, smaller, flaccid penises lengthen at erection by a greater percentage than larger, flaccid penises, with most men reaching an average size of 5 to 7 inches." Sorry about being nit picky, i just figured you would like to know. Great guide either way, very helpful
