If your sex life quietly disappeared, there is more available to you than anyone has offered.
If desire feels like a distant memory, if arousal takes forever or never arrives, if sex has become painful, or if orgasms have faded: you are not broken, and you are not alone.
I am a board-certified physician specializing in hormone optimization, regenerative medicine, and sexual health. I coined the term Sexponential Medicine for the intersection of sexual wellness and exponential medical technology, and I wrote this guide because I am tired of watching women accept “it is just aging” as an answer.
