The pelvic floor muscles are an essential part of both the male and female sexual system. For maximum sexual pleasure and optimum sexual function, the pelvic muscles must be both strong and relaxed. Many of us have chronic tension in the pelvic muscles – butt massage is a great way to release pelvic tension and increase blood flow to the genitals. Once you have relaxed the chronic tension, you can begin exercising and strengthening the pelvic floor muscles.
