Life changing. Me, Mr Happy, and those I love have opened a whole new chapter in life!First, this book far exceeded my expectations. It's science- and medicine-based, with links to reputable research and suggestions for how you can evaluate those studies and find even newer material as it's published. For that approach alone, 5 stars.I wrote my first review in May 2018. I’d read the book, checked with my doctors, and adjusted my other meds. Now I’m back, with 19 months’ experience ‘under my belt.’Results? 6 or 8 stars if Amazon would let me! Firmer, easier, longer lasting sexual response, a healthy lowering of blood pressure, especially diastolic numbers, and fewer times up to pee every night - I've checked all this out with my physician, having swapped out 5 mg tamulosin for daily small-dose Cialis.Daily like this, Cialis works unnoticed in the background, needing no attention. And I get to have the sexual and romantic life of someone decades younger.What do I like most about this book? That - in addition to the delight an easy, appropriate erection brings to me and those I love - it's about a helluva lot more than Go Take a Pill. The counseling about sex, sexual response, and being steward of a male body is some of the best I've ever read. Thost is an MD who's specialized in male sexual health and satisfaction - and it shows. I'm sure most of this book's audience is male, but I'd recommend it equally for any woman with a male partner - of any age, not just older - who wants to understand how men work, and feel, and worry, and have to fight the tendency to go silent around some of the core issues with their sex and their relationships.What else do I like, a lot? The detailed scoop on tadalafil (Cialis), the documented reassurance many men need about safety when messing with their body chemistry, and more, the well-researched potential for positive health benefits that extend far beyond erections. Tadalafil (Cialis) was first developed and researched to deal with several other significant health issues. Discovering the lovely side effect - Is that a banana in your pants? - was pure serendipity.But, boy, do I like bananas.
