A “Practice” is a rather elusive concept.
Thinking of your rubber fetish as a “practice” is a way of saying it has Purpose.
Your purpose may be to simply “feel good” or maybe it is a bit deeper. You may, for example, wear rubber to help you find your “center”. Some may think of a “heavy rubber session” as a way of cleansing themselves of the cares of the world. It may be a kind of catharsis, etc.
Purpose is a little bit different from having a “goal”. A goal, such as climbing a mountain or moving to Buenos Aires has a specific, identifyable ending. In contrast, a “practice” is open-ended. It is “what you do”, and always will. For example, the “practice” of a doctor is to heal the sick, which never really has an ending.
The process of thinking of doing your rubber fetish activities as part of your “Rubberist practice” gives them reason de ‘etre, or a sense of purpose. You do them for a reason. The more you can define or, at least explain, your purpose for wearing rubber, the more you justify and validate it to yourself and the rest of the world. (Hint: don’t get lost in psychobabble about how you got to be a Rubberist. Concentrate, instead, on why you find satisfaction in being one!)
Why do YOU “practice” your rubber fetish? Think about it!
