you should see the S&M threads between RFOF and Tangy a few months back. And I'm always vague, or at least, if I'm being obvious, I'm at least indirrect about sexual discussions/fantasies/S&M ideas.
But yeah, worrying about rep is important, unless people KNOW you are joking around. (in the case of masochism, or nu fanboyism, I'm not, but otherwise in FFtF, I usually am)
