Displaying macho traits

[Judith96a]

I'd say I did (have done) the things that interested me but shaded my behavior to appear more solidly cisgender than a real cisgender male would have to.

For example, I rode motorcycles because I like riding motorcycles and I think I'd have liked it no matter what sex I was born. But amongst other riders (male or female)
I would curtail myself from acting on instincts that I thought might show me as unmanly and thus open up a crack in the armor that would "expose" me.

That's my experience too. I played rugby because I loved it (and was useless at soccer) not because I necessarily saw it as macho. My career and hobbies are in areas that are predominantly ma!e but they are what interest me and what I'm good at.
However, 'boy me' will not, under any circumstances, wear pink or even glance at, or comment upon, a shop window full of dresses. At least, not in the company of anyone who knows him!
