I'm currently growing mine out, and still presenting male at work & around my small town. I don't do all that much different than I ever did. It pretty much looks the same as my avatar when I'm presenting either way (that was about 2 weeks ago). I WANT to do more with it, but it's at a length where there's just not a lot of options (too long for some styles, too short for others).
When presenting female, I'll sometimes pin one side back behind my ear.
Once it's long enough, while presenting male I'll probably do a ponytail, or even a man bun.
