A menstrual, flow-controlling tampon comprising a generally upright insertion tube having upper and lower ends; flow-receiving structure positioned within the tube to be bodily displaced and expelled from the upper end of the tube; the flow-receiving structure having a deployable portion configured to distend from a downward collapsed position to an upwardly deployed condition, to extend into engagement with vaginal walls associated with the cervix, and accommodation to length of vaginal barrel, following its being expelled from the tube; and removal structure associated with the receiving structure to effect withdrawal thereof away from the cervix, whereby upper extent of the deployable portion of the flow-receiving structure gathers to retain flow in the flow-receiving structure during withdrawal.
