There is nothing in this universe without rules!. There is nothing such thing as random. Yes I do in emotion but emotion exist then it has be govern my some rule. You just don't want to admit it. Thats the different case. Otherwise why most of the long distance relationship end up with tragedy. Yes I have also seen people keep their long distance relationship maintaining more than 7 years. It is because of the proper communication and understanding. But even with those Proper communication and understanding, if it continues (lets say 15 years), it will fade. Sex, Touch & Intimacy is human need. To do it, you must be in touch!
