The ancient Greeks looked at a bigger than average penis as freak show. They viewed the human body as art. There were no women nude statues that looked like Morganna or some plasticized bimbo. Men and women then were perceived as the highest form of beauty and that is why they did not sculpt bigger penises.
that's whats considered small? fuck... edit: just remembered my friend saying that romans considered large dicks as barbaric. i suppose the 'real man' in roman times had a 'sensible' sized penis.
i figured you'd carry all sizes in a suitcase, like a set of allen keys. single adjustable sounds way more efficient though. i wonder if romans had other opinions on dicks? like a veiny dick means you're friendly? i think herpes would mean you're too friendly.
