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.
We are often troubled, but not crushed;
sometimes in doubt, but never in despair;
there are many enemies, but we are never without a friend;
and though badly hurt at times, we are not destroyed.
- Paul, II Cor 4:8-9
