Wow! You know, this is the first thread I've seen where I'm worried about getting the crap kicked out of me! (probably I should take that as a sign to keep my opinions to myself, but no one ever accused me of being smart)
My best friend is over 150 pounds overweight and my spiritual adviser is at least 100 over. These are fine people, good friends and with minds not in the least flabby.
BUT, I would never think of either of them in a sexual context. (Yes, I've heard that BDSM isn't primarily a sexual activity. I disagree. It is for me.)
Faibhar's experience mirrored mine with the MENSA group in Syracuse in the early 80's. Not a good place to meet people, no intelligent conversation, pretty uniformly unattractive, and already paired off. ("The food was terrible! And the portions were so small!") I went to their meetings for the same reason Faibhar attended his munches. Playboy magazine kept referring to MENSA as "the high IQ sex club". If there was any sex going on, you couldn't prove it by me and -- yuck! -- who would want to?
On a slight tangent, my 350 pound friend tells me that "big boned" is a myth promulgated by overweight people to justify their overweight. He says that every fat person he's ever met claimed they were big boned. Of course they were -- their bones thickened from having to support all that weight.
Isn't it great to have a Forum where people will accept for just who you are?
