Reddit r/rapefantasy is full of reports, if they are to be believed, of women inviting rape, that is putting themselves in a situation where the chance of rape is high but not actually consenting, and then enjoying it at least in retrospect. I guess what I would say is it probably wasn't rape, but that doesn't mean the guy knew that. IOW it may not have been rape, but it may have been sex with an actual rapist.
