Interesting but I would like to add another point here. Professional cuddlers (www.cuddlist.com) are trained and certified to to be active/compassionate listeners and 100% present for their client and keep strong boundaries.. What you are describing is your typical 20 something hetero relationship.
What about people who are dealing with trauma, anxiety, body image issues, divorce, loss etc. If you widen your scope of the healing powers of platonic touch and take it out of the romantic realm, magical healing can and does occur.
