From the character creator of Fallen London.
Transcript
May we ask whether you’re a lady or a gentleman?
• A lady
• A gentleman
• My dear sir, there are individuals roaming the streets of Fallen London at this very moment with the faces of squid! Squid! Do you ask them their gender? And yet you waste our time asking me trifling and impertinent questions about mine? It is my own business, sir, and I bid you good day.


Then Sunless Sea gets rid of this question altogether by letting you independently select a portrait and how people address you, which can range form “Sir”, “Madam”, “Citizen” to stuff like “Uhm, err… Uh… Well…”
“Captain”, because the only thing in my pants is the under sea.
Edit: and some devils.
