But it seems relevant to anyone in a commited loving relationship.

My DW and I have experienced differing levels of libido and this is the first thing I've read that actually comes up with something that has helped us, so far, to meet each other in the middle in a healthy, loving and passionate way.
Look out for Differentiation, hug to relaxation and eye contact.
I am only part way through(for me I need to take time to absorb big stuff in bite size chunks) and I started with the abbreviated Audible essay (much shorter than the book but still pretty insightful). For me I have struggled with self-development as I have been in a little denial that I need it, however I have now a much better handle on why it matters and the benefits to us all longer term.
Oh and it's not about book bashing your partner this title puts the emphasis on you.
Totally different from a lot of traditional relationship help and guidance.
Shame David recently passed as he and his wife have such an amazing insight they reached and I love his voice and take.
Sorry not as graphic as some posts yet I hope this might offer help, as David said, every relationship has someone with a higher and lower libido, everyone.
If anyone reads would love to hear how it impacted your situation as I find others can provide insight that perhaps I missed or didn't get in the best way.
Good luck!
