Yes. It counts as self promotion, but coinciding with locktober I released a book on amazon that is all about the real, practical benefits of 14 days in chastity for you and your wife/girlfriend.
It will show you how short circuiting your sex drive and removing sex pressure from the equation will be liberating for you and empowering for her. Its grounded in research (some of which is my own) amd talks frankly about relationships, intimacy and sex, not fantasy.

I’ve never been in a FLR, I don’t think it would be for me, though I’ve read a lot about it.
I read this book with some interest, and I think it may give you some answers yo your question...
