Recently I was having a chat with Dom, and we were discussing the things you miss most about a really close and strong relationship when you out of them. Ignoring obvious things like sex, love, and having someone care for you so much. We were focusing on the little tiny things you don't notice until it is over. Like laying your head across them and hearing their heart beat. Just being able to touch their skin, during a movie, or any other time. Never having to worry about moving to fast, to slow, or liking them more than they like you. Just truely enjoying the comfort level developed between the two of you. As, Dom said it is like thier whole body has become a playground for you to just touch whenever you want without any reason to worry. The same if true of your body for them. You get to explore a human in a way you never could without being so close.
Other little things i miss:
Knowing thier smell
the millions of tiny inside jokes
Catching the knowing look of someone that knows how close you are
Missing them
Getting excited that you about to see them again even though they have only been gone a couple hours.
Having a date or a night out be something you both know you will enjoy, not something were you are questioning how things are going.
Sleeping next to someone feeling their body move and sounds they make
Having every dream almost everynight be about them and only about spending more time with them.
Not having to always seem cool and just relaxing and being yourself.
and many many more things that can only be shared when you get so close.
