I Am A Fifteen Year On And I Have A

I am a fifteen year on and I have a seven inch erect penis and I am four inches flaccid is this big, small, or normal size for my age? I have a downward bend to my penis when erect because when I was in an early stage of puberty I bent my penis when masturbating to increase the blood flow. Is that okay? And finally am I considered a grower or a shower for my penis?
