It's amazing what we will fantasize about. A sex psychologist namedDr. Justin Lehmillerrecently surveyed 4,000Americans about their sexual fantasies for his new book,"Tell Me What You Want". What he found was that one in four of us has had a sexual fantasy about a cartoon character. He also went on to say that more than half of us have fantasized about a fictional character from a book or movie and that one in three has fantasized about a mythical creature, like a vampire or Bigfoot. His theory behind the study is that we start fantasizing about fictional characters when we get bored with our sex lives and need some novelty and variety.
