I never even saw a copy of the latter but the former has some interesting ideas in it that I still find useful. I'd actually be interested in at least paging through the latter because I find stuff that is transgressive and violates taboos interesting from an academic perspective.
Both books have interesting ideas but fell short of good implementation. Much like the BoVD, Erotic Fantasy had some passable stuff in it that was interesting but extremely niche.
As a very sex-positive and surprisingly mature text about the topic of introducing and playing more adult elements and topics (sexuality, sex, pregnancy, disease, fertility deities, etc.) in a fantasy rpg, it's a pretty good reference book. In particular, it contains some pretty good writing on the moral issues and psychological consequences of charm and other mind-controlling spells.
As a resource for actual crunch, there are stats for a couple of interesting monsters and a few magic items that I liked, and one or two rules modifications that are useful, but most of the charts, spells, feats, etc., were A) unsurprisingly, far too niche for a game where more adult subject matter doesn't play a significant part, and/or B) just simply sort of boring or mechanically underwhelming even for a game more centered on those things.
It's essentially like adding a bunch of Skyrim sex mods to your pen-and-paper D&D game. (You occasionally find one or two of them generally useful, but most of them require making a conscious choice to play a certain flavor of game.)
One of the ideas I did adopt from it was being able to wear magic rings in places other than on your hands, and to adopt an additional magic item slot that covers earrings, piercings and other body jewelry - it seems fairly logical to have a pirate have a magical earring, a minotaur with a magical nose ring or a shaman with an enchanted bone through their nose...
