It's all about cuddling, folks.
There's a certain feeling you get when you're all cuddled up and nuzzling and smooching with someone you love, and... wow. Better by an order of magnitude than just holding hands, cuddling is all about contact - the tactile sensations and the warmth and the sounds are amazing.
I'm a big fan of cuddling. Sex is kind of unnecessary if you know how to cuddle properly.
