You get pressure from people talking about sex. It's hard, but you've got to resist and do what you want. It's very important not to feel pressurised into having sex when you don't really want to. Just because your friends say they are 'doing it' doesn't mean they are. There are lots of reasons why people don't want to have sex.
Some people have strong moral or religious beliefs.
Others just want to wait. It's important for you to decide what's right for you. But when a boy and girl do decide they want to have sexual intercourse, they should think about using a contraceptive unless they want to become a parent. Gay people should also think about using condoms. Condoms can help stop infections like HIV as well as reducing the risk of getting pregnant.
