OK, I'll admit, posting's been pretty light lately, but I just have to get this off my chest.
So Rod Stewart is presenting us, the listening audience, with a hypothetical scenario that IF "[we] want [his] body" AND "[we] think [he's] sexy" THEN "come on sugar, let [him] know". This, by its very nature, presupposes alternative scenarios under which we might want Rod Stewart's body while not, in any way, finding him sexy. And Rod Stewart is advising us that, should such a set of circumstances arise, he in no way, shape or form wishes to be informed.
WHY? Setting aside whether this is a likely event, why is Rod Stewart so worried about it? Is he convinced that someone who wants his body without being sexually aroused by it is likely to have intimacy issues in other areas, and he's trying to avoid such a relationship? Does he generally want to steer clear of loveless sex, finding it to be joyless and mechanical? Or is he possibly hinting at other, darker implications to the phrase "want my body"? Could he have fears of black-market organ-traffickers targeting him for their sinister schemes, or perhaps warding off demonic possession through the use of up-tempo music? I can no longer stand not knowing. I need answers, and maybe one of you can help.
(And before anyone brings it up, yes, I'm aware that there's also a potentially-implied scenario under which the listener might find Rod Stewart sexy but not want his body. This seems pretty self-explanatory to me, so I won't discuss it further here.)
