There is a new book out: "Perv: The Sexual Deviant in All of Us" by Jesse Bering. It does not seem to be quite as fun as one might think. In the book review, however, we are given some interesting results from animal studies. The reviewer notes that Freud may be largely discounted these days, but you cannot really deny that our earliest experiences can have a profound impact on our sexual cravings.

Scientists can’t readily tinker with the upbringings of broad samples of human children and track the sexual outcomes. But they can carry out a study in which newborn rat males suckle from mothers whose nipples and genitals have been painted with a lemony fragrance. Such rat pups grew up to be adults that could get fully turned on and climax quickly only with females that had been dabbed with the same perfume their mothers had worn.
Or scramble baby sheep and goats so they’re nursed by the opposite species, and then, when they’re old enough to seek out sex, let them choose between their foster and biological breeds. The grown males in this study tended to ignore their own kind; sheep spurned sheep and goats gazed past goats. They lusted instead for the species that had reared them. The females wound up much more flexible, yet still their desires were shaped by the experimental condition. Unlike a female control group brought up by its natural kin, the switched infants became adults attracted equally to sheep and goats.
To this pair of experiments, Bering adds the case of Lucy, a chimp raised more or less like a human child in a psychologist’s home in the 1960s and ’70s. She developed no interest in male chimps. “Once she’d blossomed into a young adult,” as Bering tells it, “a favorite hobby of Lucy’s was masturbating to the nude human male centerfolds from the latest issue of Playgirl magazine by carefully spreading out the pages on the floor and then placing her swollen genitals on the image of the man’s penis.”
