For women who've experienced painful penetration, menopause, chemotherapy, or radiation - or, really, for anyone who wants more size gradations to choose from in their vibrators - the FeMani vibrators (formerly Oasis vibrators) will be a welcome friend. Three distinct widths, ranging from "slim" to "maxi," can work as a set of vaginal dilators - work your way gently up, improving vaginal elasticity and comfort along the way. Each size has a dial control on the base, offering adjustable vibration.
