It's nothing so bad as that. Just relatively mundane sexual stuff as you say. I'm really not so concerned with the images themselves, and moreso am concerned with losing my job as a result. They could be hung on posters around town for all I care, so long as I don't lose my job.
I just worry that if they were sent out to my coworkers she found via my linkedin, that it would create a work environment in which they would really have no choice but to let me go.
