Von Willebrand Disease?

I'm just curious.
If I'm understanding this right, von Willebrand Disease, is a bleeding disorder.
It simply means you bleed longer. So, if someone with vWD wanted to get tattoos
or piercings, would they bleed more than the average person?
there's this thing called the clotting cascade that is the process that causes
you to clot after an injury/puncture. in vWD you're missing one of the factors
involved (the vonWildebrand factor) so these people do bleed longer than the
average person. piercing may be okay, depending on where it is (ears don't tend
to bleed much, but other places may be worse). i'd definitely talk to my doc
before a tattoo since that's more that just one poke and covers a lot more
area.
