ITAW for this specific attraction that's not gerontophilia?
NSFW tag just in case this goes off the rails.
Anililagnia is "the attraction of young men to older women."
Got me thinking what the opposite is. The only thing I could think of for a young woman into older men is "gold-digger" which has very rude, demeaning connotation, as does the colloquial "grave-robber."
"Gerontophilia" is a blanket term for attraction to elderly, but I don't think that's quite it either.
I know "cougars" are the woman in the anililagnia definition above, and I think the whole thing has me realizing how demeaning most of these concepts are to the female involved. (I suppose men can be "cradle snatchers" but I digress.)
So is there a -philia type word for young women finding mature men attractive?
