All my friends wear bras every day but I don't know if I am ready to wear a bra yet.My mum says 'Your breasts are developing', but they are really small!During puberty your vagina changes and starts to produce a clear or milky liquid called discharge.It may seem strange at first but it’s a positive sign as it helps to keep your vagina healthy.If the egg isn’t fertilised, the lining of the womb breaks down, creating the blood that passes through your vagina during your period. Girls usually use cloth, towels or tampons to absorb the blood and protect clothing.As a boy goes through puberty his penis grows thicker and longer, and his testicles move lower down his scrotum (ball sack).Erections are normal and happen when sponge-like tissue inside your penis fills up with blood – as a result of messages sparked from your brain (from a smell, touch, sight, or sound).You might also have 'wet dreams' - when you ejaculate in your sleep.
When you think you are ready to start exploring sex, make sure you understand how to avoid unwanted pregnancy and prevent HIV and other sexually transmitted infections (STIs).
Remember that sex must always be with your consent and you should never feel pressured into doing anything that you don’t want to.
It’s also OK to ask the person you are with to stop at any point if you’re no longer feeling comfortable.
It’s perfectly normal to start thinking about sex a lot more during puberty, and most people start to explore and touch their bodies too. It may seem strange when you start doing this, but masturbation is a very natural way to make yourself feel good and is nothing to be ashamed of.
Some people find that they start becoming attracted to people of the same sex, the opposite sex, or both during puberty. This is perfectly normal, and you shouldn't feel worried about it.
