Different players have different preferences. Personally, I think that a cumshot on the body or face is just a waste of good sperm that should have gone inside (I am not picky about the orifice).
Note that if you assigned anyone to a facility such as the waiting room, you do not have to use any console tricks to make her available again. In fact, it is better if you use the regular schedule overview to assign someone else (or nobody) to that facility, as this will avoid any risk of unwanted side-effects with console commands.
If you have her in your quick tracker (right sidebar), then you can also use the blue button there to free her up. As a bonus, the quick tracker also has this nice feature that if you move the mouse pointer over her current assignment, you can also see where she would be if she was not working.
