Then to make an R version from the NC-17 I do the following:
1)Take out any reference to peg A in slot B - i.e. no eplicit body parts.
2)Take out any reference to bodily fluids.
3)Read through and partially rewrite anything that strikes me (in a hand wavy sort of way) to be a little on the hard side. Sometimes this is only a matter of changing the odd word, sometimes I have to edit out whole paragraphs.
For other writers out there who do this, how do you go about it?
