If you're going to send someone your naked photo, don't do it via Facebook.

NY Daily News reports that Paul Withee, 51, a football coach for Maine's Oxford Hills Comprehensive High School, was forced to resign on Monday (February 13) after he "mistakenly posted a nude photo of himself on Facebook and a parent saw it."

NY Daily News, citing information from Maine's Sun Journal, revealed: "Withee didn't realize that the racy shot, which was meant as a private message to (his girlfriend), was posted publicly until a half hour after he put it up last week." He immediately took down the photo when he realized his gaffe, but it was already too late becase "an Oxford Hills parent spotted it." The report noted: "The unidentified parent complained to school officials on February 7."

Withee told the Sun Journal: "I'm embarrassed, I'm ashamed, I'm humiliated. I've never done anything like this before and I never will again."

NY Daily News pointed out: "School officials said that Withee was not friends with any Oxford Hills students on Facebook, and they are pretty sure the parent was the only one who saw the photo."
