A hirhur, which is ossur for a woman, is to imagine doing an actual aveira with a man to whom she is an erva. Shulchan Aruch says that it is ossur to read dirty books. Movies are a kol she ken. Hashkofos are also an issue. If there is actual abizrayhu de’gilui arayos involved, I am not sure. It may depend on a number of factors.
Hatslocha rabba!
