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.
"Tell your heart that the fear of suffering is worse than the suffering itself... And that no heart has ever suffered when it goes in search of its dreams, because every second of the search is a second's encounter with God and with eternity." - Paulo Coelho
