Diomedes is a Greek name I like, then after I did some research on Greek mythology, I learned he was a legendary warrior who was talented in using a huge spear in battle. He was so talented that his prowess with a spear could even beat a god. I felt Diomedes’ huge spear was a great euphemism for my long thick penis haha. And, 16 is my favourite number, but with a name like Diomedes, I felt the number looked best in its Roman numerals XVI.
