I wasn't sure where to put this, but here seems like a good idea. For a while now, as I've been reading Johnlock fan fiction, I've been collecting the descriptions of how each of the authors describe John's smell and taste. I've just been doing it for fun and thought I would share a few here as a lark. Interesting how unique they all can be. Sorry, I can't cite the stories these are from as I wasn't keeping track when I started...
"And his smell, like wood smoke and wool and the second pot of tea when he’s reused the leaves and gunpowder and blood pumping through his veins so close that Sherlock can feel the coppery taste of it pulsing in his own mouth…"
"He tastes like alcohol and mint and a soft buttery flavor that matches his own scent."
"John smells much more John this way, with Sherlock's nose so near his ear and the edge of his collarbone. John smells like the colour orange, pumpkin orange, but never like oranges or like pumpkins. Sherlock realizes this would make little sense to anyone save him, but after all, no one save him will ever hear it."
"He's fisting his hands in John's coat, everything teeth and tongues and heat and yes, and John needs to be closer, and Jesus the doctor tastes the way pastry shops smell but without the sugar, just warm and good and alive…"
Sherlock: "You taste brilliant. Oh, you taste like thunderstorms and bread with salted butter and copper coins."
John: "You can taste thunderstorms?"
Sherlock: "Haven't you ever smelled a thunderstorm?"
John: "You mean electricity?"
Sherlock: "Yes, but--"
John: "With bread?"
Sherlock: "Shut up, shut up, like this."
"This time when Sherlock's tongue slides into John's mouth, John starts sinking to the floor, which is really an excellent idea, in Sherlock's opinion. An utterly cracking idea, and so is the fact that Sherlock has lost his coat and the thundercloud-coloured shirt is now being pulled from his shoulders, and the way John's blood tastes with John's saliva involved reminds Sherlock of an eight hundred quid bottle of white Burgundy Mycroft once gave him after he'd refused a knighthood for the second time. There are minerals, and bits of apple, and lingering acid, and some sort of butter, he can't decide whether Irish or French. If Sherlock can think of a scientific way of bottling it, he is going to try it out."
"John smells like every warm thing in the world Sherlock has ever yet encountered, every good thing, but mostly of spiced tea, especially at pulse points. John is indispensable."
"John was kissing him. He didn't seem to have woken up, but he was kissing him just the same, lips moving smoothly and slightly parted so that Sherlock could taste a rather different flavour of toothpaste to his own, together with something he could only identify as 'John flavour'."
"He ran his nose along the side of John's jaw, murmuring his name. He liked the way John smelled, he decided. There were elements of soap, shaving cream etc., but underlying everything was a warm, slightly earthy smell which simply said 'home' to Sherlock."

And I said "dangerous" and here you are.
You. It's always you. John Watson, you keep me right.
