They may not object, they may simply not be able to comfortably say anything of substance. That's not the same thing as objecting or disliking the material. There were things I considered saying in my response that I trimmed as simply TMI (in my case, I did not wish to push boundaries further than the story itself did- given an interested and comfortable audience well outside of a work environment, I'll happily discuss quite a bit).

Or maybe they do object. It's hard for me to tell sometimes. Here in San Francisco, today was the Folsom Street Fair, the city-sanctioned and enthusiastically marketed leather/fetish fair that takes over five or six large city blocks. For several weeks leading up to it, you'll see the BDSM pride flag up and down Market St. (kind of like the gay pride flag, but black and blue stripes, with a red heart in the corner). I didn't go this year, but that's just because I've seen it before many times and don't like crowds. I forget what it's like to live in an environment where people aren't so open about sexuality (in many forms).
