I never had someone ask me that till I actually outed that I have one, otherwise, people just assume im 100% natal female.
However one of my friends got asked that question and she passes real good, but the guy was really into transsexuals and something on her gave it away!
As much as one facially might passm one might not always pass with body language or physically how their body looks!
In your case Jessica, ahem, we won't talk about what I saw but what I to me was like 99.1% female the 9% is what's getting resolved in 3 months or so for you

I know I pass really well because I get hot guys hitting on me all the time from clubs to just walking through the mall. I live in a pretty "Small minded" town.
