Transmasc

I'd like to grow my hair out more when the T starts to kick in. I've had my hair cut as short as can be without looking like a buzz cut. I generally pass well with this haircut.

Problem is, I'm not passionate about the cut. It's fine I guess but I don't feel attractive or self expressive with it. Definitely would rather pass than have a haircut I love, but there'll come a time where I can experiment more without risking my passing. I've got nice, wavy hair and it seems like it's going to waste being so short.

Any of you fellas have suggestions for long-ish haircuts/styles that are still very masculine? I've always been captivated by 60/70s men's fashion, hair included, but I'm open to other things too.
