I put yes for the biting, but with a caveat. I keep them really short to begin with. Once my nails get to a point where they go past the pads of my fingers, they are too long. I tend to clip them about once a week. Occasionally I don't, and they get caught on something, and it's just easier to bite or tear the hangnail off than it is to hunt down the clippers that my partner has misplaced.

We both do our nails, actually. He just does his toes, and prefers various shades of pink. I've got the entire rainbow in nail polish, and will sometimes mix and match and just go nuts. Sometimes I can get him to do it for me if I can't be bothered to get off LJ long enough to fix my nails though.
