I think that's part of it; we don't usually have the idea that men can be beautiful. You get the occasional beautiful man like Jason Momoa or Idris Elba (ymmv), but as a general rule the best we can be is handsome, and handsome is not beautiful. I wonder sometimes how it affects the average guy having the idea that they will never be attractive the way that women are. Guys with differing experiences, please weigh in

I am a retired art teacher and can see beauty in those images. That is sad that men do not see themselves that way. Many women do too. I have heard them say 'well he is just beautiful'. We may say some guy is hot but to me it is the visual image. One man can resonate sex but another can have just a radiance about them. Higher art. I can separate the two. The first appeal has to do with how the walk and how they talk. How they carry their body and how they respond to those around them. The other they don't have to do anything but exist.

I was thinking of great example of hot guy as Johnny Dep in Don Juan DeMarco. The beautiful man as more Brad Pitt or Paul Newman.

Unfortunately though, men posing in those particular ways ARE seen as feminine in society. We're still annoyingly bound by feminine and masculine roles
