Insertion and removal There are more complaints about difficulties in removal than difficulties with insertion. Since suction holds the cap on, it may sometimes be difficult to remove unless one knows the tricks of removal. Marie Stopes wrote that for rim caps, one should work the tip of one's finger under the rim and pull with a jerk. The idea is to release suction before pulling hard. If one's fingers are too short (and/or the vagina too long), one can use an inserter (intended for diaphragms) or have one's partner do it. Odor Since the<unk>  can be worn for longer periods of time than the diaphragm, it is more prone to develop odors which might begin to appear after three continuous days of wear.
