Um wtf? Are 당신 asking what sex is? Cause if 당신 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 질문 like this here. Anyway if 당신 don't know what sex is and your 13(i'm assuming your 13 또는 older cause 당신 should be 13 years old to be here)then I don't know. I don't know any 13 년 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 당신 want to know what sex is ask your parents! And This is? What do 당신 mean?
First,Why do 당신 ask this on a Justin Bieber spot?huh? Second,Why do 당신 ask such a 질문 to totally unknown people?Ask it to your parents! Third,How could 당신 don't know what sex is,if 당신 are 13!
