Underlining your point is a certain ambiguity in the word "graphic." If it's meant to connote "rough" or something like it, then the problematic scene is the one in the tent between the two men. If it's meant to connote the direct depiction of nudity, then the problematic scenes are the ones of heterosexual marital bedrooms in which women are repeatedly shown nekkid. There's a lot of tittie in that there gay movie, and based on your explanation it sounds like that's the reason for the punishment. The spit-lube moment may not have helped, but it seems doubtful it alone was what triggered the censors by the standards you've described.
