I am not sure about your voice but your
penis size sounds normal enough. The only
way you would know if your testicles were
either not properly descended (ie had not
fully emerged from the abdominal cavity)
would be by looking. Obviously I can't
tell you from here!

You really do need
to go along and ask a doctor to check you
out, just to put your mind at rest if
nothing else!
Perhaps a male contributor would be better
placed to advise you about this though. I
only know the little I know because
several of the men in my family had this
condition. All of them have big families
and deep voices now though, so I would not
worry too much!
