I recently read the book The Courage to be Disliked and it has had a huge impact on my stress and anxiety, and thus my libido and arousal.
I can’t wrap the whole book up here, but it is all about how to think of things. There were some aspects early on that I didn’t agree with (like the idea that trauma does not exist) but the later chapters have for me seeing things in a totally new way.
Highly recommend.
