Sexus Animalis. There Is Nothing Unnatural in Nature by Emmanuelle Pouydebat

​  Birds do it…you know how the song goes. But have you ever wanted to know exactly how they do it? Well, now you can - this delight of a book will tell you exactly how, one animal penis at a time. Why only penis? Well, because research (like life itself) is sexist and heavily skewed toward male species in all respects. Though whatever there is that’s known about female reproduction and mating quirks is featured here too.
   And oh my, is it fun. It’s so weird, so bizarre, so alien…you just can’t put it down. And, the good news is, you don’t have to, the book is slim enough to easily get through in one sitting, it took me maybe 120 minutes. It even had some lovely art, so you know just which creature you’re learning all those terribly intimate things about. And some of the things you’ll learn are terrible – animals are pervs. Just like people, in that respect. But then there are detachable (or prehensile) penises and gender swapping and some profoundly odd genital shapes that are…well, different. Very, very different. But, of course, all perfectly natural, because, you know, it's nature. Literally.
    The author, much to her credit, has struck just the right tone here, it’s science but one you just have to marvel at with bewildered bemusement or something like that. It’s disturbing, funny, strange, and, above all, absolutely fascinating. It’s also a pure pleasure to read, this NC-17 rated nature documentary you’ve been secretly searching for. Oodles of fun. Recommended.
