Short-medium answers:
I prefer mouthplay to vore. And to me, the appeal of mouthplay is its intimacy and the thrill of its precariousness. It is both threatening, but - as a fluff/romance fan - also an exercise in trust.
Whereas I’ve only relatively recently gotten into cockvore. And I’ve discovered that the the appeal there is the clear show of power, dominance and especially humiliation. The insertee can be a single person, a collective, a bus or train, or whole building - I don’t care, so long as they are miniscule in comparison to the giant. No tight squeezes; just drop, slide, disappear. Barely what you’d call a toy - more like fodder.
