Annie Proulx wants Brokeback Mountain readers to stop sending her porno fan fiction.
The film, she says, has become "the source of constant irritation in my private life".
"There are countless people out there who think the story is open range to explore their fantasies and to correct what they see as an unbearably disappointing story," she told The Wall Street Journal.
"They constantly send ghastly manuscripts and pornish rewrites of the story to me, expecting me to reply with praise and applause for 'fixing' the story. They certainly don't get the message that if you can't fix it, you've got to stand it."
