Yes, vaginal dilators will help gently and gradually to assure that your vaginal tissues are stretched. I recommend using them one or two times a day for 20- or 30-minute sessions. The more you use them, the more quickly you'll get the results you're looking for.
Dilators come in graduated sizes, starting as small as a half-inch diameter and stepping up to 1 3/8-inch diameter. Take your time, and I'm sure your first experience will be a comfortable one! Congratulations.
