Does there come a time when you can't pass as your birth gender no matter what?

Hey guys and dolls,
Is there some kind of threshold where you can't pass as your birth gender no matter what? Even if you tried - an ftm in a dress and pigtails, mtf in a tie and flattop?
Not that you'd ever catch me in a dress  , but I'm wondering if there's a point where I don't have to worry about it?

Well, gee, I suppose it differers.

Yes to some... no to others...

Yeah, I got to that point.  Fortunately it was just before I transitioned.  Also about that time I became allergic to crossdressing.  I could no longer tolerate wearing male clothes and purged my entire wardrobe.  I think I licked it this time.  I haven't had the urge to crossdress since then!

With effort, I think most of us could always pass in our previous gender roles, with the possible of exception of those that started hormones during or before puberty.  Think about it... obviously many TSs can pass as their target gender role before HRT, so it seems likely that they could do the reverse after HRT.  For example, if many FtMs pass before T even with years of E's effects, that would indicate to me that a post-transition MtF with years of E's effects also could pass as male, as they had years of T's effects not to mention plenty of practice in the male role.  And naturally that applies the other way too.

The idea of being passable (with effort) as male after fully transitioning kinda appeals to my mischievous side.  Dredge up some of my old clothes from the attic, hide my hair under a cap, wear a big jacket, speak in my male voice, maybe use some fake bushy eyebrows.  Oh the fun that could be had confusing extended family and old high school friends.

My birth gender has always been female; however, I was unable to pass as my birth sex after only six months on HRT.

I would imagine that the effects of testosterone on a female-bodied individual are quicker depending on genetics and age, of course.

I don't think there was ever a time when I was considered "normal", even in childhood, but most people simply didn't know what to make of me.

Although I could only get hormones infrequently in my early teens, it was much easier to "pass" as a girl than as a guy. As a girl, I was normal but as a guy I attracted suspicion.

Needless to say, "transition" was a snap - it was more normal and natural than anything I had experienced before.
