For those who do respect the boundaries while cuddling (hopefully most of us!) ...
What is your reason for not wanting to cross boundaries, and do you have a specific approach to keeping things platonic?
Edit: Alternatively: what is someone missing when they have problems with boundaries?
Edit 2: And just to clarify, my own boundaries are fine; I was just thinking about why some people cross them, and wanted to come at it from a positive angle.
