Here's a taste:
Invariably it happens. Sure, the workplace, the volunteer center, the family gathering, the "straight" friends, may not be the perfect place for my predilections to come to light but often they do. In my case, which I admit is rather unique, it's usually because I'm a writer of explicit materials (AKA "smut") and as such instantly become the expert in all things sexual -- but I also know some friends who just get tired of the inane jokes, the goggle-eyed mocking, the "would-you-believes" around things like body piercing and the "Dominatrix Love Triangles" on the Jerry Springer Show and just have to say something.
Once out, that's it: every stubbed toe, every sore back, every social interaction becomes shaded by their giggling discomfort. "But you like that kind of thing ("stubbed toe"), "Oh, and how did you -- wink, wink -- hurt it?" (sore back), "We know what Chris is going to do -- laugh -- this weekend. Just don't come back bruised."
They just can't get a grip on anyone who, in their eyes, likes to get hurt ....
