In the past eight years, I've had three girlfriends, two of whom I shared the fetish with and had good results. The first of those even read the CanCab novel, and really enjoyed it. The eventual breakup was amicable, and due to a health necessity, and nothing personal. We're still close friends, and text frequently. (just last night, in fact) Occasionally, I let a 'Pooka' reference slip into our conversation on how a particular woman is 'cookable', and I usually get a playful eye-roll emoji.

But I am certain she's, at the very least, endearingly amused by it, and would never 'expose' me.
The second of those was also fun in bed, using the fetish as a 'spice'. Shortly after introducing her to the fetish, she texted me photos of herself with an apple in her mouth! When this relationship ended, though, it was very abrupt and no explanation was given. She refused to have a friendship with me, and wanted no communications whatsoever. As you can imagine, this one left me feeling somewhat unclean and paranoid. Did the fetish have anything to do with it? Even if it didn't, was she now using it as justification to herself- or others- for ending the relationship? Had she spoken to any mutual friends about it? Suddenly, I was overwhelmed with paranoia, and was grateful that I hadn't texted her any of my artwork. 'Revenge porn' could be a very interesting thing in my case.
So, my advice is if you are going to share the fetish with a partner, be sure she's a good friend, and an overall good person. It's gonna take a lot of trust to make it work, and you don't want to torment yourself with doubt and insecurity if it doesn't last for the long haul.
That said, my novel (the Collens version) might be a good gateway tool into the fetish. It makes for decent reading, and you can always just say 'Hey, honey' look at this weird book I read', and see her response. If she's appalled by it, you can dismiss it as a silly curiosity. If she seems intrigued, it might be the stepping stone into some serious sexual fun.
I've attached a PDF of the 'Collens' version. It doesn't contain the added 'Pooka' chapters, and should make for safer, mainstream reading.
