A location frequently used for one's own masturbation, usually adorned with the fixtures for self stimulation such as pornography, and other turn-ons.

An entire room whose sole purpose is for masturbation. This room may include porno, hand lotion and kleenex, as well as maybe a magazine stand (so you can use both hands, or switch off if need be). A wooden chair and some candles may also be present.
"That little room under the stairs with the sign on it that says 'Jack Shack'? That's just the masturbatorium."

A location frequently used for one's own masturbation, but also a word-play on the similarly sounding 'master bedroom' or 'master bathroom'. This can be effective jab or pun that the owner of the house jacks it or whacks it alot.
Jack: "...And finally here at the end of the hall, are the bedrooms."
Me: "Oh, and might I assume this one is the masturbatorium?" ::smiling::
Jack: "Wha--Excuse me, what did you say?" ::agitated::
Me: "May I assume this one is the master bedroom?" ::speaking slowly, for clarity::
Jack: "Why, yes it is." ::relieved::
Me: "Well, I can imagine you spend alot of time in there." ::smiling::

A room in a house which is smaller than a Man Cave that is dedicated to the manual release of tension and stress via masturbation. These areas are a guilt free zone for partaking in the practice of self love via pornographic websites.
My wife and two kids were contributing to my already insurmountable stress levels, so I had to retreat to my masturbatorium for an hour and rub one out.

A place to masturbate, alone, or with others. Example is from a Playboy adult limmericks's column circa 1969.
Today's modern movie emporium
Is not just a cinamatorium
But a highly effectual,
Heterosexual,
Mutual Masturbatorium.

Any place used for self pleasuring ie: masturbation on a consistant basis, particularly appropos when self inflicted pleasure is made into a full blown event. A bed, a restroom stall at work, a movie theater or even your car can be a legitimate masturbatorium.
