Look, just in case this is a serious question, and you are concerned, I'm going to tell you. By the way, you obviously have access to the internet and there are plenty of web sites that will give you the information. A girl gets pregnant after a boy/man places his penis into her vagina (which is between her legs) and releases sperm into her. She can only get pregnant about 3-4 days out of every month. A girl will not get pregnant by simply kissing a boy, holding hands or hugging. Generally, a girl will not get pregnant if both the boy and girl keep their clothes on.
