To me it is obviously all of these, but also I don't think the bottom two really exist as opposites. I think there can be a lot of overlap between being as close to another person as possible and a violent, animalistic act. Two people become the relationship between their bodies in that space of extreme contact and participation in a thing that necessarily is composed of both of them merged into the act. There can be an temporary erasing of both selves into the act. This isn't to say that there isn't a distinction between "making love" and "rutting," just that sometimes they share aspects.
