Dora Wilk Series has some. As narrator, Dora, gets more and more infatuated with Miron, we're getting more and more descriptions of how handsome he is. Then there's Baal, who becomes Dora's good friend. When she's Dreaming of Things to Come, her dream starts with Baal banging a girl and description, while not being porn-like, is very... informative about him. Spoofed, though, when girl ends up assassinating him.
Twilight, obviously, has its share: A good three-quarters of the book is Bella telling us how perfect and handsome Edward Cullen is.
Bella's dad lampshades it for Dr. Carlisle Cullen, saying that it is a good thing he's happily married, and that the nurses have trouble concentrating around him.
Tall, dark and handsome Louis from the Charlie Parker Series is constantly the subject of paragraphs describing how incredibly attractive he is, often in contrast to his short, aging, unattractive partner Angel. A flashback to his and Angel's first meeting, when he comes out of the shower dripping wet with only a small towel protecting his modesty, is particularly notable. In universe, he constantly has waitresses and secretaries hitting on him, and is easily able to flirt information out of women when necessary.
Even without a movie, or even an illustration, Garrid still manages to be this for Tales of the Frog Princess.
Finnick Odair in The Hunger Games, in-universe. Of course, this series being what it is, this trope gets deconstructed when it's revealed that President Snow has been forcing him to prostitute himself because desirability = profit.
Alec Scudder in Maurice is an example of this. He's gay, he's up for getting down with Maurice and their relationship doesn't end up with anyone dying.
Hornblower from Horatio Hornblower series is Mr Fanservice even on paper. Ladies are known to be attracted to men in uniforms, but Hornblower gets a Shower Scene every now and then, too. As a captain, Hornblower is known to his crew for taking a daily shower by having a couple of sailors at the pump with a hose—even in the Baltic where the water is freezing, and an incident partway through has him moving around the deck without any clothes on for about half an hour. The first time this habit appears chronologically is in Lieutenant Hornblower, where it's described in great detail: the hoseman pumping a stream of water on him, casting a towel aside, standing there naked in the sunshine, an amused crowd gathering to watch and Mr Bush's musings that it might be pleasurable despite being unhealthy.
In The Wise Man's Fear, Tempi's default costume is a suit of skin-tight "mercenary reds." Of course, he spends a considerable portion of the expedition not wearing a shirt, or entirely naked.
Cedric Diggory, whose good looks bordered on being a running gag during his time in the series. The fact that he's a total sweetheart (to the point that he tried to forfeit a Quidditch match after his team already won) certainly helps. Even infamously whiny ghost girl Moaning Myrtle took notice. Too bad he dies at the end of the book.
Sirius Black was once this in his youth, though all those years imprisoned in Azkaban for a crime he didn't commit robbed him of that (Harry observes that there are some vestiges of handsomeness left on his face, though).
Dimitri from Vampire Academy is described as a "god", and his well-toned physique is frequently mentioned.
Reqi in Wise Phuul finds himself showered with attention from both men and women. It doesn't do any good: he's asexual.
