In his own videos and at cons, Doug Walker is the kind of guy who'll eagerly swirl his tongue around a lightsaber, striptease at panels, flirt with anyone who has a pulse, and regularly gets teased for his Oral Fixation.
Exploitation video reviewer The Cine-Masochist is tall, muscular and handsome, wears tight fitting t shirts (and one time wore one made of MESH), wore heavy eyeliner on more than one occasion and most recently had a gratuitous shirtless scene as "Random Naked Serbian Indian", implying that he was completely nude.
Quinn from Demo Reel. Most of his scenes consisted of him in the background, half-dressed, showing off his muscled arms and snarking in an Irish accent.
Speaking of well-muscled, Tacoma was a fit black man with camera-focused long eyelashes, a ridiculous amount of flirting back with Donnie, and spent his his last couple of episodes in a Belle dress that demonstrated how nice his shoulders were.
Donnie DuPre. Wears a lot of t-shirts that show off his arms, gets objectified by Carl's camera to make a Male Gaze point, wears eyeliner and lipstick without making a fuss, asks for slash from the fandom, uses his best physical traits to get what he wants and the people who he hits on are mostly other men. Oh, and did we mention he's also a Fantine-level woobie sweetheart?
Carlos the Scientist from Welcome to Night Vale is an in-universe example; we never actually see him (because it's a sound-only series) but most characters who do see him generally treat him like a Living Aphrodisiac, most notably Cecil (who borders on being a Stalker with a Crush up until he and Carlos become an item) and Old Woman Josie (who gushes over Carlos' perfection along with Cecil).
Cecil Baldwin (the voice of in-universe Cecil Palmer) once suggested that Carlos would look something like a "Brazilian supermodel".
Anthony of Smosh gets way more shirtless scenes than Ian, and is often the one who crossdresses and wears tight skimpy outfits in most of the videos.
Random Assault: Most photographs of Matt have him naked or topless at the very least.
Corin Deeth the III of Kakos Industries falls neatly into this category for his wonderfully deep voice alone though it's what he says and how he says it that has drawn in more than a few admires within and beyond the show. Even the official website describes him of "sounding dreamy".
