Can you tell me, my penis size is normal or not... my age 30years, in erect position 4.6 inches long, 4 inches girth... solution also. What is normal?

There is no "normal" and if you're not happy with what you have, there's nothing you can do about it anyway.

What is normal?

Again I will tell you that there is no normal size. They are all different.

Ok, you are not really 30 are you ? 12 or 13 ?

Grown men know that there is no average size, some men are very large and some are smaller,

For sex size does not really matter, women seldom organism with sexual activity but with foreplay, the finger ( or tongue or sex toys) will do more than the penis every will.

And there is nothing you can do to make yours longer or shorter,

What scares me is if you really are 30 and sitting them with a ruler measuring it
