a monogorifice describes a fictional orifice occupy-able (metaphorically) by a single partner.
The word monogorifice is a combination of the words monog (short for monogamy) and orifice.
Hi Tim, nice to meet you, are you currently the soul occupier of Jessica's monogorifice?
"Jared", "Yes Binx?", "If I had a monogorifice I'd wanna shove you in it!", single tear
It's ok, you can spend the night, my monogorifice is currently unoccupied ::wink wink::
