What do you miss the most physically in a long distance relationship?

People always talk about missing their partner emotionally in long distance relationships, but I feel like the physical side is rarely talked about. Not even just sex… I mean the small things. Holding hands, random hugs, falling asleep next to each other, even just sitting close while watching something. Sometimes those small things feel like the hardest part of the distance. I’m curious what others feel about this. What’s the one physical thing you miss the most when you’re apart from your partner?
