growth in size

[utkarsh]

is it possible if be rub our penis our size will grow

[Short Circuit]

Nope, it does not matter if you rub it or not, it will grow during puberty.

[Rayquaza]

When you say rub do you mean masturbating? Huh?
If you rub your penis while it is flaccid, it will grow causing it to become erect, and fill with blood, if you didn't know that. Otherwise, if you mean make it bigger then no, nothing you can do can make your penis size bigger, it will grow on its own during puberty.

It might get swollen from the rubbing...but that won't be permanent growth
