Um wtf? Are آپ asking what sex is? Cause if آپ are then this isn't the right place to ask. Go ask in the Sex and Sexuality club. There are little kids on this site and a lot of little kids like Justin Bieber. So it's not the smartest idea asking a سوال like this here. Anyway if آپ don't know what sex is and your 13(i'm assuming your 13 یا older cause آپ should be 13 years old to be here)then I don't know. I don't know any 13 سال older who doesn't know what sex is. So if your not 13 please leave this site and come back when your old enough. If آپ want to know what sex is ask your parents! And This is? What do آپ mean?
First,Why do آپ ask this on a Justin Bieber spot?huh? Second,Why do آپ ask such a سوال to totally unknown people?Ask it to your parents! Third,How could آپ don't know what sex is,if آپ are 13!
