Yes your size is around average for the age of twelve. No offense but your girlfriend was probably laughing because she might have saw bigger penis's in her life (if she's already seen yours at the age of twelve). I'm twelve and my penis (erected) is about 11.5 cm (or 5 inches) so you might want to look into some Viagra if your already getting laid lol. Good luck with that!
no this is really good you should be very happy
In erection, it is not abnormal. This size is in the "average" for a human being. The fact you are young does not change a lot.
You know what ? you are normal.
Be happy ur not asian.
Yes it is more then enough.
Stop worrying so much.
ya ... don't worry ... am 17 years old and my dick is 16.5 cm now and it was 15.5 cm last year ... And the penis will continue growing till you finish the puberty which is when you reach about 18 years .... your penis is about average which is 5 inches and you can reach 6 inches min. when you end puberty :D
It ranges between 40 cm to 60 cm as the norm. (15.5"-23.5")
well its about normal it depends if you have hit puberty
i would say that's abit big but all penis sizes are differant so don't worry about it.but remember a big penis is good.lol ;)B):)
The average thickness of a grown man's penis is 2-4 1/2 cm across, 2-4 cm from top to bottom, and 10-15 cm around
yes.
yes that is around the average length.
5 inches (which is about 13 centimeters) is the average size penis on humans.
He would be in mid puberty.
i'd have to say NO, that is a good thing but-it all depends on your fathers' size......
Yes. Men frequently check each other out in the locker room and at urinals. They tend to do it secretly however, because some guys will get angry.
