Get over yourself. Even if they don't do porn, the kids will make shit up about the ones they find attractive. Or are teachers not allowed to be attractive, either?
There was a rumor at my high school that one of the math teachers used to pose for Playboy back in the day. Whether she did or not (I never found out, and who cares), she knew her shit and was a damn good teacher.
Let people live. For crying out loud.
