hi, im 15 and very curious about if my penis is normal, as most teenagers are i hope ^.^

anyway, first off... is my penis a normal size

normal - 9.5cm
errect - 15cm
errect girth 4cm

ontop of the 9.5 (end of the head) on floppy, i have another, around a cm of skin thats just excess.
when i pull the skin back, it goes from the top, all the way backwards from where it joins bellow the head (very, idk the word :P flexible? lose?

aswell as that, i THOUGH it was normal for your errect penis to be at a slight angle, mine being like, curving upwards slightly. Is this bad or?

wondering if im normal? :S
