I'm recategorizing my images and created a 'worksafe' tag, mostly to keep my guro collection out of sight of innocent browsers, but then thought perhaps I should have it live up to its name.

Are girls in casual underwear worksafe? Sexy underwear? Stuff that's not underwear but still very risqué (seen 'He is My Master'?)
Are naked girls with no visible sexual features (tactical posing, 'absent nipple syndrome', etc) worksafe?
Are various genders groping girls' chests through their clothes worksafe?
Are fully dressed quadruple amputees worksafe?

I can provide pictoral examples upon request.
