I have found over the years that the best cuddlers have the following characteristics/capabilities. Disclaimer: this list is just from my personal perspective and in no way suggests that is the best way or only way to cuddle, that all cuddlers should have these characteristics or that other clients have the same viewpoint.
Is “present” and fully engaged.
Relentlessly client-centric.
Naturally affectionate. It’s in their DNA.
Able to provide unconditional acceptance (subject to the fee and rules).
Self-confident and assertive.
Understands “emotional labor.” Uses it verbally and physically throughout the cuddle.*
Initiates platonic touch. Spooning is passive contact. Touch requires the hands.
Receptive to and encourages platonic touch from the client.
Physically flexible to accommodate various positions.
Emotional labor has recently taken on negative connotations, with which even the academic who developed the concept disagrees. I would suggest pro cuddling is 80% - 90% emotional labor, by contrast, pro therapeutic massage is 80% - 90% labor labor.
Interested in what characteristics are important to others, but again I am not attempting to mandate or regulate anyone’s behavior or cuddling experience. Happy cuddling!
