When I was in labour with my daughter, the midwives spent twenty minutes trying to force my legs open to get me flat on my back with my legs up. There was no emergency. It was so they could get a better CTG reading. I physically resisted for as long as I could and verbally told them to stop. They didn't stop until I gave up. After that they did other things without my consent, but I did not they to stop them again.
I complained to the hospital and they have done nothing. I complained to the police and they told me there must have been an emergency. I've complained to the NMC and the CQC. I hope they will do something but it's a long process so I won't know for a long time.
The police used to say that domestic violence was a private matter. They used to say that if you got in the car/went into the apartment/were drinking then you must have agreed to it. I think this is exactly the same type of justification, applied to equally criminal behaviour.
I don't think my experience is abnormal. I think this is fairly routine. They thought that when I gave up that meant I consented.
