In brief: After puberty
There is usually a fairly rapid period of growth of the penis itself which occurs during puberty.
One of the first steps of puberty is the growth of the testicles which get bigger to accomodate all of the hormonal changes they are meant to support. These hormonal changes include growth of the penis itself. Penile growth outside of this usually stops at the end of regular growth between 15-20.
