The meaning of sexual orientation, also known as your sexuality, is a way to describe your sexual feelings. It includes who you are attracted to, either romantically or sexually, who you choose to have sex with, what type of sex you like having and what turns you on.
It can take time to work out what's right for you - so don't worry if you're not sure yet! Although there are some labels - like gay, straight and bi - not everyone fits into one category or another and that's absolutely fine.
