How do you and spouse sleep?

Its both curiuos and sometimes a problem. My gf likes to sleep with either her arms and body dd over me a or I d over her ,kinda like spoons. Now I can go on like that for a while but after a certain amount of time I need to either curl up alone with pillow, go to the bak to back position , i just have a problem with constant contact all night long. she syas i am avoiding contact which i dont as i do snuggle for a while but eventually roll over. what do you think?
