The easy answer is no! By age 16, statistics say that most of the people in your class at school haven't ever had sex (if they have already had sex it's illegal anyway!). _
People lie about sex. People lie about who they've had sex with, how many people they've had sex with and at what age they lost their virginity (the first time they had sex). _
It is very importnant to remember that people lie about sex so that you do not worry that everyone else seems to be having sex if you're not. _
Different people feel ready to have sex at different points in their lives and it is very importnant never to have sex just because you think everyone else is. It is often the people who always talk about having sex that haven't had sex anyway!
You should NEVER have sex if you don't want to (whatever your age and whoever they are). It is ALWAYS illegal to force someone into having sex.
