I've struggled with intense dyspareunia for probably 20 years. After just 1 week of use, the sensation of tearing disappeared. The set I ordered came with exercises to do. Those in conjunction with the treatment worked immediately. I have no issues with tampons of all sizes. The only advice I would give for purchasing is I did not need sizes 2 to 4. I did need sizes 5 and 6. That may just be my body. But the smaller sizes were no pain at all; similar to a tampon in size and sensation. So when trying to decide which sets to purchase, that might help someone. I really struggled deciding if I should get these thinking it wouldn't work for me. I wish I had purchased these years ago.
