Attracted To Your Relative?

I know it sounds disgusting and immoral, but have you ever been attractive to your sibling? Your cousin? Some other relative?
I was flipping channels and came across an episode of Jerry Springer where this guy fell in love with his sister (and wanted to marry her sef!).
So has anyone ever felt romantically attracted to a relative?

me too. @poster did you put d pix to distract us from the topic?
