This guy is doing a tremendous blowjob, but the question is wether he could do the same without them poppers. I think he could, he wouldn't really need them. If horny enough he'd do the same without. Well, at least I would, or halfway choke trying (lol!), certainly with a cock like in the vid. When looking at his eyes I'm afraid he's about as far gone as his throat is loose. But fully in agreement with your conclusion.
