I am a journalist based in San Francisco, working for the German weekly Die Zeit and other outlets. I came across the recent issue of the American Journal of Bioethics which has several articles on the ethics of quantified relationships, using apps like sex trackers, gamification of back rubs etc. to improve your romantic life. See the editorial here: http://www.tandfonline.com/doi/full/10.1080/15265161.2018.1423793
I'd like to write about that, so I am looking for people, especially couples of course, that use this kind of tracking and quantifiying in their daily lives. And in case you're wondering: I'm not going to make fun of it, it's a great topic that I would like to know more about. You can contact me here or through firstname.lastname@example.org.
