I swap it pretty dramatically from really long to short, bangs/no bangs, about once a year. Every few years I'll test out something pretty different and maybe start playing around in a different style than previous. Did a lot of Pixies in my late teens, side part medium length in my early 20's, and now it's long centre part shags since my late 20's. Started colouring it this year for the first time because I wanted to play around with it in a new way, too. May be a gender thing (or an ADHD thing, lol), but I just get bored of the same and like testing out new stuff against my face shape. Helps I have a hair dresser I love and have gone to for years, so we have great rapport. I think it's more common among women to play around with their hair, though I feel like this is changing a bit.
Having said that, the majority of ppl I know definitely stick with something they feel comfortable with, irregardless of gender. They'll maybe slightly modernize their cuts over time, but otherwise stick to the same part, same colour, similar length for years on end. I feel like a big outlier in this regard, and I don't even think I'm that crazy out there.
