On the topic of kegels: they were recommended to me as part of my therapy for (secondary) vaginismus. My psychosexual therapist advised I do them several times a day before starting dilator treatment. Although I don’t do them so much now during the day, they’ve actually helped me a fair bit with dilating and with attempting penetrative sex – contracting and releasing the muscles can help during the process of penetration. I think I was initially advised them as part of my treatment because it allowed me to regain a feeling of ‘control’.
