I agree, and would add that not having someone to exchange touch with is harder when you're attached, as I unfortunately have first-hand knowledge of I'm out of that relationship now thankfully, but the lack of affection that is so important in a relationship stays with me.

To answer BigBear's original post, yes, I have in past relationships loved the closeness, the tenderness of cuddling up close to someone and just being. Hands idly roaming, exploring each others bodies just to enjoy each other's touch, not necessarily to go on to full blown sex.
