All very interesting but if you think this is a picture of a consensual encounter then I think you are being wilfully obtuse. Being a Brit this picture has barely registered with me before but looking at it for more than a second you can see that she is limp, not holding him back. If it were consensual here arm would be around his neck. Her jaw is clearly clenched tight and he is holding her like a bear. Whoever the people in this photograph actually are I know what I see, so the main point of this post stands.
