It's less about seeing the body exposed and more of the restraint and control factor, also a tactile, sensory thing with the latex. Even if they're completely sealed up, you know there's someone alive inside and you can see them struggling and overwhelmed with shiny goodness
And no, to me body bags are horrifying because they're clearly used as and designed for preserving corpses, not as bondage restraints.
Although given all the weird shit I've seen online it wouldn't surprise me if someone was legit turned on by body bags, gross
