If you kiss on the first date and it's not right then there will be no second date. Sometimes it's better to hold out and not kiss for a long time. I am a strong believer in kissing being very intimate and the minute you kiss the floodgates open for everything else.
Beyond that I seem to be compelled to write science fiction rather than fantasy or mysteries or some other genre more likely to climb onto bestseller lists even though I enjoy reading a wide variety of literature both fiction and nonfiction.
