Terminology becomes important because so many terms are attached to the default societal view. I find myself struggling because I have a picture in my head or a feeling, but once I attach a label to it that is used by the society at large, the picture can get skewed. However, everyone still desires to communicate, so the basis has to begin somewhere.
Lately my SO and I have been discussing the term FWB. To us, the phrase has come to mean a friendship that exists because of the benefits. Nothing wrong with that, except that neither of us is built that way - and yet we have absolutely no issue with having sex with friends. Therefore we have turned the phrase around: benefits with friends. Changes the emphasis a bit.
