You can get blue waffle by having to much sex. And I read somewhere that it hurts because it spreads to the anus and when you get "wet", its very very smelly. Prostitutes are most likely to get blue waffle. And to prevent it, you need to shower everyday, and take care of yourself.
Thats pretty much all I know about it, hope it helps. :)
