Autogynephilia is Blanchard's word so you might as well either use it the way he defines it or make up your own word for whatever alternative idea you want to communicate.
Autogynephilia as Blanchard defined it is not a paraphilia real women have.
Examples of AGP Blanchard has noted include stuff like guys he's talked to who've sat in on knitting classes and get erections because knitting is a woman's hobby, or getting erections because they're helping their cleaning ladies clean the house thereby behaving like a lowly woman.
Actual women tend not to get sexually excited by the idea they're in a knitting class or that they're doing women's chores. That sort of excitement is predicated upon seeing the female sex as alien and exotic, something actual women can't do since being female is something they've experienced for their entire lives and is as familiar and mundane to them as is possible.
Here's Blanchard himself explaining this:
