No that is not normal actually that's something that needs to get checked out. The parent should be alarmed/notified about that, because maybe the child needs someone to talk to or help from someone.
its perfectly normal
NO!
hi my friends boy is almost 4 but she is concerned that his penis is only 1cm is this normal or should she have him circumsised.he is quite a big boy apart from that.
NO.
A normal 24 year old would have a penis of between 5 and 7 inches long.
No. You don't let your child do that and especially not at 13. Time to set boundaries. This is very inappropriate.
A 5" penis is perfectly normal.
7 incheserect
That's tiny
It is normal for an 18 year old guy to not have any female friends. This is just a stage.
around 10 inches is about the norm for a 26 year old.
its your body do what ever you want with it. im 15 i do every so often and many of my friends do to. Decide it yourself , it's ur body ! And u like it without hair so it is o.k. More and more 13 year old boys do it . U have a fine feeling after shaving .
Depends on whether your penis is erect or flacid. Also, if you are Chinese I wouldn't worry - you're ahead of them in terms of penis size.
