It depends on how good your lawyer is. When sexual harrsassment suits started to pop up there were a lot of high profile cases where a lot of guys going to jail. These days they take those claims with a grain of salt. If it's just your word against hers then you should be fine. If she has a bunch of evidence to back up her claims then prepare to fry. Just make sure you don't take it for granted and talk to a lawyer if you're ever accused.

FYI my dad has beaten two sexual harrassment cases. Both of them were probably substantiated because he does make some lewd comments but ONLY when it's someone that can take it as a joke and gives it right back. Be careful of what you say in the workplace. Even if it's just fun and games now you could really end up getting screwed down the road. One of the girls that accused him came back TWO YEARS after she quit and brought it up.
