This is really where innate gender (spectrum) and social construction gender (binary) collide, so it's a tricky and complex issue. Forgive me if I muse a bit, it's probably gonna get long.
My first thought goes to musicians, especially from back in like the '70s and '80s. David Bowie, Robert Plant, all those hair bands and stuff that totally pushed gender boundaries. As far as I know, and I'll admit I don't know much about what was going on personally for them, but they all were secure in their masculinity but seemed to enjoy exploring some aspects of femininity. Have you ever watched a Led Zep concert video? Plant was SUCH a chick, but he's still living life as a dude and doesn't show any signs of trans-ness that I'm aware of these many decades later. Bowie looked better in a dress and makeup than most of the women in my family.
Romans and Scots wore kilts (and whatever the Romans called them), and the Romans made fun of the German pants-wearers. High heels were invented for men. There was a whole time period where men wore really frilly outfits with ribbons and lace and wigs. Peacocking tends to be seen as a feminine thing in our society but it hasn't always been historically so. In the animal world it's often the males who have the pretty colors and stuff. Since humans don't really have much in the way of that sort of thing naturally then both sides get to do it if they want.
I think guys painting their nails is becoming more of a thing, and I'm betting it will become more and more so over the next however many years. Pretty colors are nice, dresses are comfy, sad movies are an emotional release. There are lots of reasons to want to do these things that don't necessarily have anything to do with innate gender.
The other option is the gender non-binary thing, but you said being seen socially as female would trigger your dysphoria so I'm thinking it's not necessarily that. Something to keep in mind though, as we're pressured to fit into neat little boxes and yet that's simply not how people work.
As for me personally I've experienced this going in the other way, no question. I was watching some TV show and the main character was all dressed up in an "old west" outfit that looked -really- good and I was like..."Damn, I'd love to be that cool". And it definitely tripped me up a bit as I'm still figuring out the whole self-definition thing (aren't we all).
I think it comes down to us bumping up against society's rigid definitions of which traits belong to which gender and good ol' internalized sexism. It doesn't help that very little research has been done on gender. Also the fact that the environment we live in is a far cry from where humans spent most of their time evolving makes for some pretty weird stuff going on.
If I could give a piece of advice it would be do what makes you happy and try not to worry about labeling it or rationalizing it or trying to figure out why. Easier said than done though, I need to work on this myself :p
