Training your pelvic floor muscles will not only improve your posture and tone your tummy, it can also improve your sex life. Your muscles producing orgasms are located in the pelvic floor region. These muscles are full of nerve endings which are sensitive to touch and pressure. The intensity of your orgasm depends on how strong these muscles are. So, by doing your pelvic floor exercises, you increase the flow of blood to the pelvic floor region, which in turn makes the nerves more sensitive. It also works the other way too. An active sex life is also exercise for your pelvic floor. This is true as an orgasm is a series of contractions, which in themselves are mini tightening exercises.
