What’s the nosiest question you’ve ever been asked?

I'm a lesbian and used to go to a weekly gay night as a student. One week, my straight guy coursemate/frenemy was there as part of a group supporting their friend who had just come out as a gay man. My coursemate clocked one of the regular drag queen attendees from across the dancefloor and started asking me all kinds, starting with "does she use he or she" (fine), then stuff like "what surgery is she going to get", "does she have a dick". I said something like, "I have no idea, I've never looked. As far as I know, almost anyone in here could have a dick. As far as you know, I might have a dick". And I blew his tiny mind as he questioned, wide-eyed, whether maybe I had a dick. I've never answered that one for him. Interestingly though, maybe 5 years later this guy started wearing drag "as a joke" then did it more and more, then came out as gay and said the drag was part of exploring his sexuality. So while what he asked isn't okay, I guess in some way it was for research. This is much milder but the old lady from down the road who constantly asks me when I'm harvesting my fruit trees in a highly disappointed way, because she 1) tells me directly she peers over my garden wall and 2) knows I give vastly fewer fucks about my fruit trees than she does, is also pretty damn nosy.
