I'm really struggling to remember when I learnt about consent. I don't recall it being from my parents. I remember studying it in a criminal law module, but obviously I already knew what it meant at that point. I think if I had a child I'd struggle with with teaching this because I'd fill it with so much waffle "I know you're not an idiot, or a sociopath, and I know that we establish no means no when you were a toddler, but we need to cover it off again so that you don't accidently find yourself in a position where you've raped someone". I don't mean to be dismissive of this, because I do appreciate its important, but I can imagine many parents would think the same.

Now if I saw behaviours in my child that prompted me to think this might ever be an issue, or they expressed concerning attitudes about sex or consent, then that would be different, there'd be a clear reason for having the conversation.
