From the book We Did Porn by Zak Smith:
I think men must seem really like dogs to women-- hungry and large, often slobbering-- as a species, unpredictable and sometimes dangerous (the dogs of war, the dogs of doom) but as individuals, predictable and clockwork and cute (like puppies, like hounds), and, if you spend enough time with them, each with a different personality (babe hounds, faithful hounds). Some are tiny and harmless, some are harmless and big as bears, but all have predatory, long-boned bodies with teeth and claws essentially made to hunt and hurt smaller things. To deliver yourself sexually to an unknown one must be like putting yourself at the mercy of a strange, large, imprecise, and hairy animal that you can just only hope is well-trained. Straight men should imagine how much differently they'd behave if their lovers were-- to scale up-- wolves.
