OK, I'll slow down a bit, fine for me as well!

Rape is mentioned in some of the excerpts I've posted above. As for sexual violence preceding cannibal acts, there is a reflection somewhere else in the book, where the author comments that many of the historical reports of cannibalism we know of come from European explorers, missionaries and such, who often had a rather Victorian attitude. So for them, writing about bodily violence, even cannibalism, was much easier than writing about sex, whether consensual or not. And indeed there are hints in some of these accounts that obscene and sexual details were left out. So there's probably a lot that did happen but of which we'll never know.

Though I don't think cannibalism as such was particularly "sexy" or driven by sexual desire. We aren't usually aroused by eating animals, and I don't think these historical cannibals were aroused by eating people. They seem to have enjoyed eating them, maybe because meat in general was a rare delicacy or because eating this particular meat gave them a feeling of superiority and power, but there doesn't seem to have been anything particularly sexual about it.
