So I'm a fan of this website and I thought it would be amusing to analyze what tropes my fursona is an example of. Here's the comprehensive list:

A Man is Always Eager: Or make that "a horse is always eager."
Anatomically Impossible Sex: Duke is a horse. Enough said.
Animal Stereotypes: The Horse. Duke fits most of these to a T. He is noble, majestic, powerful, passionate, loyal, courageous and beautiful.
Barefoot Cartoon Animal: Duke doesn't wear shoes
Bear Hug: Most of Duke's hugs are this.
Big Eater: Duke eats a hundred pounds of food a DAY.
Bigger is Better in Bed: Comes up a LOT among muscle furs. Horses doubly so.
The Big Guy: Example of a Class 2.
Born Winner
Charles Atlas Superpower: Somewhat. Duke does get a lot of his inherent strength from his genes, but his intense training has vastly expanded this.
The Charmer
Curves in All the Right Places
Does Not Know His Own Strength: Especially in his younger days.
Ethical Slut: Duke gets around, but he usually genuinely cares about his lovers and has high standards when it comes to his professional work.
Expressive Ears: *Earperk!* *...earfold...*
Fake Nationality: Duke's Texan accent is an affectation.
Famous Ancestor: Duke's sire was a literal Titan.
Fur is Skin: Duke uses posing oil liberally, and has no trouble despite possessing horse hair. Somewhat justified in that he does explicity shave the way human adult models do.
Gay Cowboy: This pretty much defines Duke as a model.
Gentle Giant
Handsome Lech: Duke is unashamed about his reputation as a guy who gets around.
Hates Being Touched: Subverted oh so wonderfully hard.
Hello Nurse: A male example.
Hot God: Duke's sire.
Huge Guy, Tiny Girl: Same sex version with Duke and his mate.
Human Pack Mule: Subverted in that Duke actually enjoys it.
Hunk
I Got Bigger: Duke went from 6'1 and 220 in high school to 7'0 and 500 by the age of 25.
The Immodest Orgasm: To the point of SHATTERING WINDOWS.
Inhumanly Beautiful Race: Horses in the fandom tend to be portrayed as this. Duke certainly regards his species as this.
Interspecies Adoption
Interspecies Romance: Obviously. It's the furry fandom.
Leaning on the Furniture
Like a Fish Takes to Water: Duke and bodybuilding.
Macho Camp: Duke's body ALONE qualifies.
Man of Steel, Woman of Kleenex: Duke can bench press trailer truck beds. He can do trailer pulls with six full semi trucks. It's a wonder he doesn't utterly liquify anyone he tries to sleep with.
Manly Gay
Martial Pacifist: Arguably not so much in that Duke has any combat skills but that putting him in a situation where he was forced to resort to violence would be a very bad idea.
Muscles Are Meaningful: VERY much so.
My Instincts Are Showing: It's generally a bad idea to approach Duke unnoticed from behind. Duke also becomes suspiciously docile when groomed with horse brushes or has a bit and bridle slipped on.
Neck Lift: Has done this on a few occasions, although more by the shirt collar and occasionally more of a bicep lift.
One Head Taller: At 7 ft, Duke tends to loom slightly over his lovers and friends.
Pec Flex: And how!
Power is Sexy: In the form of super strength.
Power Walk: And it is DELICIOUS!
Rags to Riches: Duke's childhood was one of considerable poverty on a wolf preserve, and it was only after he broke into the adult modeling industry that he became wealthy.
Raised by Wolves: Literal example.
Rancher
Ready for Lovemaking: Pretty much defines Duke's entire profession.
Sapient Steed
Seme: Duke falls into this category of anime/manga male characters.
Sex God
Sex is Cool: Duke's raison d'art.
Sex is Good
Shirtless Scene: Duke is fond of these.
Sleeves Are For Wimps: None of Duke's shirts have sleeves.
Sliding Scale of Beauty: YMMV on this one, but even conservative estimates have to put him at world class levels.
STD Immunity: Duke is always immaculately clean. Everywhere.
Stock Animal Diet: The Horse. Duke loves his carrots, apples, and the occasional sugar cube. He is a hay connoisseur.
Straight Gay: Unless those daisy dukes give it away. ;)
Superpowerful Genetics: Justified in that his sire was immortal.
Super Toughness: Including the ability to take full-on fisticuffs, plywood, baseball bats and metal pipes to his core without even flinching. Being hit by a vehicle leaves bruises.
Super Weight: Duke qualifies as a Level 3.
Tall Dark and Handsome
Underwear of Power: Duke's signature golden thong.
With Great Power Comes Great Perks: Duke doesn't use his superhuman strength, toughness or beauty for anything other than mundane activities.
World of Cardboard Speech: Semi-averted, in that Duke has never given a speech about it, per se. However, he has commented on the fragility of most things at one point or another.
Women Prefer Strong Men: Same-sex version in most encounters with Duke.
