Despite the negativity of my prior post, there are women who are attracted to CDs. I know some from this site, if nothing else. I think one of the reasons they are difficult to find is that feminine men are extremely rare out in real life, so many women who could be attracted to a feminine man / CD have never met such a person (that they know of), and so they don't know they could be attracted to them. I wouldn't ever expect this to be common, but I have talked to cisgender women here who have told me they enjoy CDs.
I think the closeted nature of most CDs, femme erasure - particularly that of femme men, and transphobia make this seem more impossible than it actually is.
