Hi I'm 23 years old and I am worried about the size of my penis, it is 12 cm in length and 3 cm wide, though I do not know if I have measured this properly. My questions are, can this be considered a "normal" or healthy penis size? And is there anything I can do to change it? I'm 1.92 m tall and I know penis size is not reated to height but it is embarrasing. I have not had sex at all, and this is one of the reasons.
