Sooo pretty fundamental question, (hence the rather vague thread title) can physical relationships be meaningless, or is it impossible to have physical relationships that don't register on at least some emotional level. People seem pretty divided about this, as a quick test, think about which of your friends you could kiss (reasonably seriously) and then act just the same with them as before, im gonna bet its not everyone, even if you do know them well.
Films and other media tend to dictate that they must mean something (eg. The American, or No Strings Attached)
