Troll!
For starters, you'd burn your clit right off if you put nicotine down there because the only way to do that would be a tobacco product. There's no place to buy straight nicotine.
Secondly, he'd taste a tobacco product and it wouldn't be nice because it would burn his mouth too.
How?
Obviously you've never had a cigarette, chewed tobacco or snuffed any.
Enough said.
