Hello.  Brand new member.  I've been obssessed with male actors' crying scenes since I hit puberty (thirty-odd years ago). Can't explain it, don't know why, and have never told a living soul about my strange addiction.  But now I see that I am clearly not alone. :-)
This forum is such an incredible resource.  I have been avidly reading older posts and watching so many new and exciting video clips. Thank you all!  I hope to be posting some clips of my own soon. 
In the meantime, I wanted to mention some very recent crying scenes.  There's been quite a few really good ones, and that's pretty much what led me here. Probably no YouTube links yet, but can be found on On Demand and probably the shows' websites. 
1)  "True Detective", episode 8, "Form and Void".  It was already mentioned in another post, but I think it bears repeating because Matthew McConaughey's monologue/breakdown is AMAZING.  (And the entire show is one of the best things I've seen in years.)  Final ten minutes of the episode. 
2)  "The Following", episode: "Sacrifice".  Shawn Ashmore has a complete and utter meltdown, last five minutes of the episode.  Major tears and sobbing, dissolves into the arms of Kevin Bacon. Extremely raw and real. 
3) "The Walking Dead", episode "Still". About halfway through Norman Reedus' Daryl has a very moving, guilt-induced breakdown, sweetly comforted by Emily Kinney's  Beth. 
4)  "Believe", pilot episode, about twenty minutes in.  The hero encounters the telekinetic little girl for the first time and starts crying without even realizing it.  
I apologize if these have been mentioned before.  
Happy to be here.
