When in bed with your honey, can you sleep through the night holding on to them (or, have them holding onto you) or do you need your space?

To candoodle or not? I can do the snuggle thing at first, but, then you need for them to stay on their side of bed. I can’t sleep with someone holding on to me. My girlfriend, on the other hand, is like a worm in that she finds me wherever I’m at in the bed and snuggles in.
