Worse is his posture and mouth btreathing.
How about The Rock and Jason Momoa?
I’ll add Orlando Bloom to the list.
Whereas I saw the posted picture of him at the piano, and thought “OK, yeah, he’s not bad, who is he? Wait, some of the captions are talking about the Big Bang Theory? I should recognize him, then. <spend a moment trying to figure it out, while reading further> Wait, what, Howard!?”.
Apparently, he cleans up well. Or dirties down well. Or something.
Personally, I can discern male attractiveness well enough to be able to tell that most Hollywood actors are more handsome than most everyday folks, but I have a very hard time telling who, among Hollywood actors, are hotter than whom.
It was a fistfight over a girl.
As a fan of old, dead people, I’ll add mid-1960s Patrick McGoohan as my masculine ideal. No one could raise one eyebrow like he could…SO fuckin’ suave, man. And the “no kissing women” clause in his Danger Man and Prisoner contracts proves that his Heart was Pure.

Even older and deader is comic film genius Buster Keaton, definitely the most handsome male comic film genius in history (although Chaplin also looked good in mufti). Buster had those dreamboat eyes.
And a skilled actor, to boot! 
Yeah, he almost had me reconsidering my path, but then Leslie K from two blocks over walked by in a tee shirt and shorts showing off her legs up to yea and I forgot what I was talking about. No, really, what was I talking about? Something about looooong slender legs, I think. I do know what a second glance was–something she never gave me.
McGoohan’s female stars helped the no kissing clause because often they weren’t as pretty as he.
If you did an image search of this guy on Google, you’d probably just wrinkle your nose in disbelief. But when I watch Brantley Gilbert in his music video Bottoms Up, I get so turned on.
Oiy! Watch you say about my sweet baby, holding a sweet baby, who’s holding a sweet baby !
I can’t disagree with anyone who’s been mentioned here, except maybe Simon Helburg. I love the guy, would date him if he’d have me, but I don’t consider him overly attractive.
Johnny Depp was unnaturally gorgeous for a long time. Still better than the average bear but life has been rough of late.
I’m say Jon Hamm is at the top of my list.
I’m shocked there aren’t any Poldark fans piping up and mentioning Aiden Turner. Between him and Eleanor Tomlinson there’s something for everybody to gawk at on that show.
George Clooney in his prime? Ludicrously handsome. I’m not gay but for George, I could be convinced.
Young Tom Selleck. Young Cat Stevens. Naveen Andrews from Lost. Benedict Cumberbatch. And, against my usual type, Chris Evans.
I’ve never found Brad Pitt terribly attractive. I don’t get Jason Mamoa, but I do think Hugh Jackman is very attractive.
StG
Zac Efron.
Jimmy Garoppolo (from the world of sports, maybe cheating there).
Good. Less competition for me and Dung Beetle.
Of course it’s Brad Pitt.
Simon Helburg? Really? Guess I’m not a good judge of attractiveness in men.
That’s a “no” on Simon for me there, dawg.
The Rock is likeable - he seems warmly genuine and trustworthy, which is a huge compliment from me - but not particularly sexy to my eyes.
Jason Momoa, however, makes me kind of giggly and I start stammering a bit, and that’s just from looking at a picture. If he smiled at me in real life I can guarantee my cheeks would get very flushed and I’d be all flustered and not even really know WHY.
I think Beck nominated Robert Downey Jr.? Good call, girl. Was just rewatching Sherlock Holmes and loving how every movement and line gets imbued with subtle humor - he’s just so damn funny in an understated way, that I find very panty-dropping. He has beautiful eyes (those eyelashes, jesus!!) but the fact that they seem always to be laughing about something or twinkling at a joke he’s made internally to himself takes them over the top into “mesmerizing” territory.
Wentworth Miller back when he was on “Prison Break” made me feel all sorts of ways:

Finally, I always knew he ain’t catchin’ what I’m pitchin’ but Matt Bomer has been my favorite eye candy for a good long while. All that beefcake in “Magic Mike” and he was the one I wanted to see.* Probably wouldn’t much care for “White Collar” if he wasn’t the star, but I’d watch him twirl a fedora onto his god-kissed hair with that flourish and impish little grin for hours.

- I lied somewhat. Matt McConaheyyy needed to strut around shirtless in more scenes.
Cole Alexander.
For the same reasons I named Cyndi Lauper over Debbie Harry: Easy enough on the eyes, nonthreatening, well-spoken, but I admit it’s his art I find irresistible. The heart wants what the heart wants.
