Birthday present for a significant other that doesn't want anything

Belle

Hey guys! I would love to have your opinion on this or any ideas you might have. So my love's birthday is coming up, December 26, and he says he doesn't want anything. Which I understand is something some people say, but I know he truly doesn't want any more stuff. He's really not a fan of his birthday at all so I'm struggling a little because I want to do something nice and special for him without drawing a lot of attention to the specific day because I want to respect his wishes and not make him uncomfortable. I'm thinking a date night. Something just the two of us, especially since we haven't actually been on a proper date. I would just say for him to come over and we could watch a movie but I'm afraid we wouldn't actually get the time to ourselves because I have six siblings that all still live here. So do you guys have any other ideas or think the movie night at home would be good? Have any of you been through this or have this issue when it comes to your guy?
