Vaginismus is a condition characterized by involuntary muscle contractions in the pelvic floor, making penetration painful or impossible. This can occur during sexual intercourse, gynecological exams, or the use of tampons. The exact cause can vary and may include physical, psychological, or emotional factors. Women experiencing vaginismus may feel anxious or fearful about penetration, which can further exacerbate the condition. Treatment options often include pelvic floor physical therapy, counseling, and the use of vaginal dilators to help desensitize the area and reduce muscle tension.
