I have had long hair most of my life, I have cut it short about 3 times in my adult life for different reasons. At this point I don’t see myself ever cutting it short again. I have always worn it down unless it’s very hot I’ll put it up. I’ll also put it up if I’m working in a dangerous environment were it might be damaged.
One of the big problems is there is not a lot of references to hair styles for men with long hair. There are also very few accessories for men with very long hair. My hair dresser is into guys with long hair so I am very fortunate.  I have a permanent braid that I do every week. I at times add several braids to the rest of my hair and just let it fall in with the rest of my hair. Those braids I don’t fasten, I just let them unravel on there own.
I was wondering if anyone had any Ideas or Pics of hair styles for men outside the traditional ponytail or braid that men have been doing for years.

Maggie's suggestions are the same as I would have.  I've known very few men that are comfortable with wearing their hair in a bun, but I like the look. 

A lacer is one more option to consider.  Natural Rogue has one in his avatar picture.  It gives the appearance of a braid without doing the braid.  Most of the lacers I've seen are made of leather with plastic, wood or metal beads. 

Good luck and let us know what works for you so we can pass it along to others!
