That was my experience too. When I first started flossing I'd get some bleeding (in no small part because my lack of flossing before caused the gum at the bottom of the tooth to be inflamed). Bleeding is very infrequent now. I personally use those plastic flosser sticks. I cannot figure out just the string. But I floss once a day every day and have for years. Just remember to floss each tooth twice in a V shape. You need to do both sides of the tooth and the bottom.
