Girls

It's not natural to obsess over anything, first of all. It seems like you're looking for comfort but you're looking the wrong place, and no woman wants a guy who's that attached (literally). Wanting to be held like that is generally the result of not getting enough affection (or getting too much) through life, but instead of projecting it onto women you would be much better off talking to a professional about it. I would say that as long as you have this "need", any relationship you have is bound to fail because no one wants to be on the other end of that. Also it could manifest into something far more dangerous if left unchecked.
