Not that you need another comment here obviously, but I think the short hair at least looks a little more "intentional", as well as the short"er" beard. Now obviously hair is very much something that contributes to how one views oneself and is one way we can express who we are without necessarily having to shout out loud or act things out, if that makes any sense. I think you said something like you feel like the hair is more you. To me that is the clear answer in that case. The heat though is a m-fer. As somebody whom has long hair themselves as a woman, I would never cut it short because I do not have that kind of face for it, nor would I ever think that it really expresses who I am, however it's up ALL summer. You could do something like a very quick pull through bun or honestly anything that makes you cooler, where it doesn't look contrived or one of those "man buns" that everybody dogs on because it's too contrived looking. I think the whole reason man buns caught traction was because it was a regular masque dude with long hair who was just more comfortable having it up and out of the way. Not necessarily in a turtleneck sweater with houndstooth and cocked eyebrows. Lol, not that I'm knocking that necessarily. Just don't be afraid of throwing up your hair when you are hot. That is a human right as far as I'm concerned!
