maybe a bit niche, but there is an appreciable difference between tickling a nose with a feather, and tickling inside a nose with a feather.
in this case, i actually find tickling on the edges and outside of the nose to be hotter when it elicits a heavy reaction. gosh, your nose is so sensitive! this biiiiig fluffy feather brushing up against it so gingerly...it's just the bare edge of your nostrils, and you've already got to sneeze this bad? oh honey...your poor little nose is sooo helpless...
you're just gonna sneeze and sneeze and sneeze....
