From All About Romance:
AAR’s sensuality ratings have come under discussion lately due to the changing nature of the romance industry in general. With the recent proliferation of racier novels, what was once declared Hot may now be considered barely Warm by our readers. The language used in love scenes, once a deciding factor in rating, has also changed drastically in recent years. Quaint euphemisms such as “manhood” or “heated channel” have fallen by the wayside.
If we update our sensuality ratings in response to changes in the industry, what sort of changes should we make?
One issue under discussion was possibly adding another category after Burning.
. . . .
Is it shocking to read a review rated Warm, only to find language once considered very blue when you read the book? Conversely, some readers may be disappointed to purchase a book rated Burning because of language or one delicately described incident of alternative lovemaking, when their hope was for something more raunchy.
. . . .
My suggestions are:
At no point in the book is lovemaking (or rape or other sexual violence) described beyond mention that it has occurred. There may be kisses or petting, pregnancy, mention of a wedding night, etc, but at no time is the reader present during a love scene or forced intercourse.
Straight sex only, Male/Female only, with no alternatives involved. The reader is present when sex occurs for an unlimited number of times, written with gentler euphemisms or correct terminology (orgasm, penis, erection, bundle of nerves, etc).
