Backing up Caryopteris' first comment, don't get trapped into comparing yourself to other guys; it is the ladies' opinions that matter here. Men seem to compete rather uselessly over penis size, since bigger is not better. If a woman has a vagina five or six inches deep, that is all she wants in a man, not nine inches. It would hurt. Besides, the nerves in the vagina for sexual sensation are all in the first couple of inches. A man could have a penis two inches long and still give a woman an orgasm.

You are also normal in the masturbation category. I've noticed that guys that always do it exactly the same way have more trouble adapting to intercourse, which stimulates a wider area. So don't try to be too precise and efficient, lol.
Question A: A perfectly normal size.
Question B: Two or three times a week is also pretty normal, or even a slightly modest amount at age 16 when the hormones are the most strongly flowing they will ever be in your body.
