I have daughters, and I have spoken to the eldest, who is 12, about this. I told her about the BBC article, in particular the health risks. I have always spoken very openly to her about sex because I want us to be able to have these conversations.
I told her that when she is older, she should never let partners do this or anything else she is uncomfortable with, and she should never be afraid to, or be made feel guilty about, saying no.
I was coerced into doing things I didn't want to do with predatory men when I was younger, and I don't want the same for her. No-one spoke to me or my peers about consent when we were teenagers. Girls were either pilloried for being slags or else for being 'frigid'.
