Struggling to understand?
Welcome. Start with the beginning of the FAQ thread which stickied to the top of this board. Take your time. There is more to this than meets the eye and, at the beginning anyway, it's not easy. The cuddle world tends to reward patience, effort, respect, self-awareness and thoughfulness.

Here's the basics. Platonic meaning friendly/non-sexual (I'm only adding that because you'd be surprised how many people don't know the definition and I'm not talking about the people who ignore it)
If you have any specific questions please ask. That question is a little vague. It would be better to know what aspect you're to struggling understand.
