I do have Confirmed Bachelor, and I thought maybe this was why the doctor at Camp Forlorn Hope kept calling my guy "buttercup" and complimenting him for being "pretty." I'm figuring, okay, I can roll with this, just give me some dialog options to flirt a Doctor's Bag (ahem) out of this guy, and I'm good. But no. When I started hearing decidedly womanly grunts out of my character, I realized that the game forgot what gender I was playing. I might even be able to roll with that if it weren't for the beard.
As I have said previously:
Actually I believe I have the answer, do you have the Confirmed Bachelor/Cherchez La Femme perk? Or Lady Killer/Black Widow? The former is unique interactions and dialogue with the same six: Male to Male/ Female to Female; and the latter is opposite six: Male to Female/Female to Male. Both provide +10% damage to the six of your perk bonus.

The perk Confirmed Bachelor (for Males) means unique dialogues between your Male character and other Male NPCs.
The perk Cherchez La Femme (for Females) means unique dialogue between your Female character and other Female NPCs.
The perk Lady Killer (for Males) means unique dialogues between your Male character and other Female NPCs.
The perk Black Widow (for Females) means unique dialogues between your Female character and other male NPCs.
By "unique" I mean the sort of dialogue you are having difficulty understanding the content of.
All of the above include +10% Bonus damage to the six specified in the perk.
