Maybe they’re not scientifically proven to help with vaginismus, but for me they were a miracle!!!! I tried 1st with nonmagnetic dilators, and got nowhere. I couldn’t even get the smallest 1 in. I tried for a week, and ended up crying every time. I was ready to give up, figuring I was a lost cause. But then I decided to order the vuva magnetic ones. I figured I had nothing to lose. The very 1st time I tried it, I was able to insert the 2 smallest ones with no pain at all. I couldn’t believe how easy it was! I ordered the next 2 sizes the next day. By the end of that week I was able to insert the second to largest dilator! (5.5 inches, 1.25 inches wide.) And I was never even able to insert a TAMPON before that! It could be entirely psychological, but whatever it was, it worked!!!! Ever since starting to use the vuva magnetic dilators, I’ve been hopeful that I could overcome this. AND I haven’t cried once! Except for tears of joy when I was able to insert the dilator for the first time.
