When you begin writing romance, one of the big decisions is heat level. So, how do you decide? For me, it's write what I read.
Sweet romances. I read them, and I'm comfortable writing them. I do have a problem writing the ones which adhere to Christian market rules. I accept that life has swearing, drinking and gambling. In the Christian "sweet" market, these don't exist. Sometimes I forget and have to go back and take out mention of a glass of wine with dinner.
Sensual romances. I read a lot of Harlequin category romances. So this is the heat level I tend to write at--sex happens, but the word "cock" never occurs. When it comes to reading and writing, I live happily in euphemism land.
