(NSFW) Do you wear underwear under your pajamas?

This is probably safe for work, but just in case I put the label on it.

Please tell us if you are a girl or guy.

Does it matter what type of pajamas? For instance I wear underwear to sleep if I am wearing a long T or nightgown, but I don’t wear underwear with pajama shorts or pants.

Have you always worn them or not worn them, or has it changed as you got older.
