I came across this podcast the other day, and it's fairly short (about 4 minutes), but it talks about possibly being addicted to love:

It seems to me that the feeling we have during cuddling is very similar to feeling loved, due to the release of oxytocin, and it made me wonder if it's possible to have a cuddle addiction. For dating relationships, I've heard about people who are "serial monogamists", who like to start new relationships for the excited feelings you get at the start of a relationship. Seems like 'cuddle addiction' could be a real thing. I seem to remember seeing at least one or two threads since I've been here about whether it's possible to cuddle too much - Someone said they had a cuddle partner who he spent so much time cuddling with that it was starting to disrupt his daily routine and life overall. It's good to keep things in a healthy balance.
