Nudes for long distance bf

My boyfriend and I are in different countries for Christmas unfortunately, and he’s asked for some nudes to wake up to tomorrow for Christmas morning. I’m totally okay with that and want to do it for him, but I have never really sent nudes before and I don’t know what kind of poses or anything I should do. It just feels awkward because I’m by myself instead of with him, but I want to do this for him. So what should I send?
