It's a phenomenon called narcissistic supply, which makes narcissists seek excitement and drama to give them access to admiration, adoration, and notoriety. Any time you say "no" or set up a boundary on their behavior, it's just a red rag to a bull: they hate being told what to do. This can lead to some hilariously House Of Cards problems where they're trying to manipulate everybody behind the scenes (narcissists are also terrible gossips).
Sometimes that's OK, as it means they encourage you to do things you've never done before — but other times, it means your own personality and preferences get squashed. But they can't relax; they always need to be in charge of everything, from holidays to dates to life in general.
Their innate sense of superiority means that they regard boundaries as a challenge — Don't Speed On This Road, You Can't Go In There, This Is For Members Only — they get a lot of pleasure from manipulating their way past restrictions like that.
The key to solving a difficult relationship is to identify the natural sensual behavior you bring to an interpersonal relationship and recognize the behavior in the other person(s).

Why enter into any relationship blind to what may lie just ‘around the corner’?
It's easy to throw around the word "narcissist" around without really knowing what it means: Whether you're talking about Kim Kardashian's selfie obsession, Madonna comparing herself to Martin Luther King, or Kanye West, er, just being Kanye, it's easy to forget that genuine narcissistic behavior is a recognized mental condition.
They also take a lot of risks (because, hey, rules don't apply to them) and are fearless, which makes them great dates.
