Not that specifically - but i had other nervous tics - like scratching at my arms constantly till they bled and pulling out my eyelashes and biting at hangnails, etc.
Whether your nervous habit of lip-licking was caused by the CSA episodes directly or not, it is very likely that it was a reaction to stress in your life. It wouldn't surprise me though. I think that often kids who are abused will develop self-harming habits, some more serious than others.
