Even if you take the explicit sex.out of this comedy/romance title, it will still bring surprises about the characters around the main character. There is a lot of rollercoaster feelings about the past of the individuals that is brought back before time someone gets laid - and that past is not really sex-related. It seems as if the story contrasts present with uncontrolled instinct and a past of innocence (although naughty innocence at times) that is easy to a reader to relate to.
Not as profound as Milo Manara's erotic work, but goes way beyond than incredible sex artwork. This was one of the best stories I've read. If you are 18 years old and above, I strongly recommend checking it out.
One thing I did not see here and I was relieved is that no female characters were raped in the production of this story.
