Waxing poetically for a moment: My very first guy back in HS had one with a distinct curve to it. But what did I know; Back then, I was still (impersonating being)a guy. All I knew was that his cock with its upward curve and elongated head looked absolutely marvelous, compared to the straight and boring "pole" that I had :) Ahh memories ;) That should have set off so many alarm bells, however there simply wasnt any language to explain it back then,,.
