I've recently been wondering about sex. I know what it is, but not how it works and the stages of sex. There are several terms like 'ejaculate' and 'pre-ejaculate' that I don't understand. I don't want to talk about this topic with my mum, as I find this sort of thing really awkward to talk about.
I'm also curious to know whether sticking your own finger up your vagina and moving it up and down is sex or not
