I like to touch strangers on the dance floor. It's a socially sanctioned, nonsexual form of touch. We dance for lots of reasons, including the exercise, the music, the friendships that form, the conversations, etc. but I can't pretend that I don't enjoy the hand holding and the dips and the swaying in each others' arms. We need human contact to thrive, and this is one form that I enjoy greatly. (I also enjoy dances with people I know well.)
I have never been to a cuddle party but I am guessing it serves a similar purpose. I would find it a little weird just to touch without the context of a dance or other goal, but if it works for some people it doesn't bother me. I'm not sure how it would be related to polyamory though, or the purpose in including it in a polyamory conference. Doesn't really have anything to do with love or relationships!
