It's funny, this - so many words to describe the same thing,” she smiled...“Penis is simply an anatomical appendage, as exciting as a finger or a phalange. A willy is something small and flaccid, and at least slightly humorous. Prick is the organ as viewed with distaste, perhaps with so much as to describe the entire body it’s attached to, like a dick, but more so. Phallus is a symbol of fertility, but my favourite...is the cock, which is only ever the hard, real thing, unleashed and ready to dive head-first into any waiting orifice. Or hole, while I’m in thesaurus mode.
