How much time do you spend flossing? Do you do multiple passes?

I floss fairly quickly. I go over each tooth at least once, but some days I go over them twice. Kinda gross, but sometimes I look at the floss between teeth to see how much gunk is on it and go over the same tooth until the floss comes out clean. Don't floss too much or too hard in one go though because the floss can cause tiny cuts that can lead to infection.
