Another thought -- along the lines of my first paragraph, one common term that's used to insult sex-positive feminists (by feminists who don't identify as sex-positive) is "fun feminists". The idea being that we wouldn't hold our position if it weren't "fun", or that we've been distracted from the "important" stuff by the "fun" stuff, or that we get undeserved attention for being more "fun". This obviously makes some of us feel like we have to prove that we're not that fun :P
