I was talking to a single friend recently and we both agreed that what we miss most when not in a relationship is not sex (although...who wouldn't miss that?:wink

its intimacy and affection. A hug from a friend ends up feeling like a precious gift when you've been on your own for a long time. I just listened to a radio 4 play about a mother who has a surrogate baby for her daughter and she talks about the lack of physical contact in her life and there is a really moving scene where her daughter kisses her cheek after ten years of not touching her.
Absence
Separate in my solitude
how loud is this quiet!
The absence of your voice
deafens me and leaves
my untouched body restless.
arms folded, pacing familiar floors
I hug myself as if cold
hoping to recall the warmth
and ghost of your embrace.
