What are the dilators for?

Dilators are basically very smooth, hard dildos, used by women who have had vaginal surgery, tearing during childbirth, an episiotomy, etc. Because scar tissue is not elastic like pre-surgery vaginal tissue and may shrink as it heals, women can use a dilator to slowly stretch the scarred area. Smooth plastic vibes or smooth silicone dildos of a reasonable size can also be used for dilation.
