2. Physical Contact
When you enter a long distance relationship you have to realize that physical contact would be limited. Sex or even a hug will be agreed upon from earlier. No one will be there when you need a small hug to get you through the day. Sex will be infrequent and although you might be looking forward to the passionate times when you are together, it can be hard to deal with the absence of physical contact for long periods of time. You need to make peace with that before you agree.
