Like many young women, when I started having boyfriends, I wanted to have sex. But like most in the UK, I was taught that sex= penis in vagina sex (PIV).
In reality, there are many ways of having sex. But if you are taught that having sex means having PIV, the you accept if you want sex, PIV is an automatic part of it.
So do women who think thsi meangfully consent to PIV? I don't think I did. To meaningfully consent I would have to know I had the choice of having sex with a man, and not having PIV. To meaningfully consent, I would have to be able to have a boyfriend who accepted it if I said I did not want to have PIV.
You can't meaningfully consent, if you don't know you have a choice, and if you can't say no.
