Now that I know better, I skipped all the sex scenes. They did nothing for the plot and I enjoyed the book so much more. 4 stars.
I wish ebooks nowadays came with "hide" tags. If a sex scene, or a family reunion with gazillion kids, or a lengthy scenery description do nothing to move the plot along, put it in "hide" tags and mark "Bedroom sex" "Kids behaving badly" "Purple landscape" and so on. Those who are interested will read them. Those who don't care will enjoy the story more.
