A vaginal insert formed from a composition that, prior to introduction to the vagina, has the physical properties of a liquid, semi-soft gel, paste, foam, or viscous material so that it can be effectively delivered to the vaginal canal. After introduction into the vagina, the composition will expand and/or solidify into a semi-solid or solid structure to substantially fill the entire “H” shaped space of the vagina and a portion of the rugal folds along the length of the vaginal canal. Upon solidifying, the composition defines an insert that, in one embodiment, is suitable for use as a tampon and, in another embodiment, is suitable for use as an incontinence device.
