1. A fluid collection assembly, comprising:
a fluid impermeable barrier at least defining a chamber, at least one opening, and a fluid outlet; and
at least one porous material disposed in the chamber, the at least one porous material including at least one of:
a protrusion extending outwardly from the at least one opening, the protrusion exhibiting a shape that does not correspond to a shape of the fluid impermeable barrier and a shape of a majority of the porous material, wherein the at least one porous material includes the protrusion before the at least one porous material is exposed to one or more bodily fluids; or
a fluid permeable membrane, a fluid permeable support, and at least one expandable material that expands when exposed to the one or more bodily fluids, the fluid permeable membrane extending across the at least one opening, the fluid permeable membrane positioned between the at least one expandable material and at least a portion of the fluid impermeable barrier, the at least one expandable material positioned between at least a portion of the fluid permeable membrane and the fluid permeable support, wherein an expanded portion of the at least one porous material exhibits a shape that does not correspond to a shape of the fluid impermeable barrier and a shape of the majority of a porous material when the at least one expandable material is expanded.
