Is my penis normal, part II

[The One and Only...]

In the previous OAO penis thread, I pointed out that my penis is slightly curved. That turned out to be okay, and gave me some bonus points for being a little unique.

In this penis thread, more will be covered:

1) Can someone tell me how large the average 15-16 year old male's penis is? Mine is larger than the average adult male's, and I suspect that it will grow larger as I get older, so I thought that I could put together a mathematical module based on proportions which would allow me to predict the height my penis will likely become (for those who are interested, my penis is a little longer than 7").

2) Is it normal for me to shoot so far that I could hit my face/chin/neck if my penis were pointed in that direction when I masturbate? Doesn't that seem a little... far?

3) How long is the optimal penis length, assuming the cardinality of pleasure in women (women answer, please)?

Thank you for reading this thread.
