Improve your sex life by targeting basic fundamentals of cellular energy, hormone production, and pelvic floor function. There is a specific muscle that does not get attention for improving erections in men. The Ischiocavernosus Muscle is directly involved with erectile hardness and angle. This is still relatively unknown and understudied. There aren't a lot of ways to strengthen this muscle. I found a specific way to directly target it. I hope this book improves your sex life and carries over into many other areas.
