I just tend to only bring up things at appropriate moments, and some things only around certain people -- like my Prom Horror.
But since the feminist movement, little girls are now given more gender liberty than boys, so much of my past really isn't that "gendered" -- think about it, how many people here honestly believe that female-identified tomboys are somehow perverse, or that little girls "shouldn't be" into science or dinosaurs. If I'm being read as "man", then my Science Genius Girl past doesn't seem weird, I just leave out pronouns and the rare gendered comment my parents actually got about it; if I'm being read as "woman", people will simply think my parents were awesome for encouraging me and breaking outdated stereotypes.
So, yeah, i don't "edit" much, but I'm sure that's easier for me than it is for most TS women.
...and when I do pass as "man", I tend to get read as "flamer", so saying things like "my first boyfriend" just gets responses of "woah, you're parents were cool with that?" To which I can honestly say "yes, they were". This may seem contradictory when considering some of the other stories i have about my family, but I figure most people assume I was just using shorthand for "well... my parents weren't surprised, let's put it that way". And ex-boyfriends of my adulthood don't surprise anybody. If anything, it may surprise people I meet if I were to edit these bits to reverse genders, or they may silently be inserting "boyfriend" when I say "ex".
