I learned a TON from this, not just about sex and desire, but also about psychology and social sciences in general: how emotions work (fight/flight; tend/befriend), how stress changes the way you engage with the world, how patriarchy has perpetuated myths about sexuality, attachment styles in relationships, the importance of self-kindness and mindfulness, emergent theory of mind (as a flock of birds!) and probably more things that I'm not remembering offhand. Just so many really fascinating insights! It's super engaging and interesting to read and definitely worth it if you want to understand more about what makes you / your partner(s) tick.
