Will my penis grow after puberty?

Need clarification: Did you mean will my penis grow after final height? When did you hit puberty and how old are you now?

Puberty: During puberty, your body gets transformed from being a lean boy to a big young adult. The body part that concerns a lot of boys is their penis. Yes, your penis will grow during this period. I have seen penises grow larger in young men into their early 20s. So don't despair.
