I think there was a time a few decades ago when publishers encouraged their writers to put sex in their books. I find it totally distracting and end up skipping many pages. Also, it fills up the word count, I think they want the books to be like 600 pages long so they are looking to fill it out. I also remember a time when it was considered daring and rebellious to put in graphic sex, but those days are long gone. Henry Miller was considered scandalous - Tropic of Cancer banned! But we have all seen those words in print nowadays.
