I’m writing a book and for everyone who doesn’t have a partner in the book, I was going to go back after finishing to assign sexualities

The only one I had written as a joke was that the drill sgt character is straight, but he is only that way at work and when he gets home he goes into sub mode and does exactly everything as his wife commands, and he essentially just roleplays as her when he goes to work, but looking back I feel like I might be offending somebody
