The applicator has orientation indicators to allow the user to properly orientate the insert within the vagina. The applicator also has an inwardly curved radius on the leading edge to reduce any resistance during insertion and withdrawal of the applicator. The applicator may also have at least one vent to facilitate expulsion of the insert or to deliver medicaments or lubricants inside the body cavity. The insert applicator has a rounded cross-section to maximize the available space for the insert, while also facilitating insertion of the applicator into the vagina.
