I've heard that it is not uncommon for men to get erections during or after battle due to adrenaline and increase in blood pressure. I can imagine that this might be very uncomfortable in a full suit of armor. Maybe these enlarged cad pieces were an attempt to address that.
Or they just had them made large so that their descendants think they were more endowed than they really were. Like paying an artist to make your portrait prettier
When did people start thinking big wangs were cool? Cuz I've seen some ancient Roman and Greek stuff that had the opposite view of large genitals with sentiments like "a man with a big penis is only good at having sex, and having sex is basically useless."

There's a set of Henry's armor hanging out at the Met as well. I was pleasantly surprised to bump into it en route to see the gaudy-as-hell frame they put on Washington Crossing the Delaware.
Since we can't meet Henry himself, meeting one of his suits of armor is the next best thing. It wasn't nearly as fat as the paintings would suggest.
Sir Edmond of The Rusty Dongs: "Oi, fit bird, I wanna take you 'ome and give you a ride in me full kit until you come down with the rusty nail and Jack the Ripper."
Imagine being a regular foot soldier in this era, wearing some leather armour and maybe chain mail. Then this steel behemoth comes at you with his pals.
