Basically, I don't like touching people that I don't know. That's why I always thought I didn' like to cuddle. why do I need someone else to stick to me? It's hot, it's uncomfortable, I over think about every movment I want to do,  who needs it?
But - cuddling with someone I love is soooo nice (it also releases aucsitocin, which make us feel happy and strengthen our bodies). Someone even once told me that evolutionarily people who like to cuddle survive better because it communicates sexual contact and procreation.  I do not think it is true but it is a nice thought.  So I do like to cuddle, just not with anyone...
