I would say tho that the female of the species can be as sexually aggressive as the male, and that sis' comments could be applied to either gender. I think it's more a person's insistence that it's not transference, that it's a true attraction, that it has nothing to do with therapy, that indicates a person's willingness and or ability to process and use these feelings in the service of the therapeutic analysis or analytical therapy. If it's "just" therapy, maybe the depth won't be there.
