I absolutely love Megsies and Harrys PDA. Hope they continue with it.
For me hand holding and supporting backrubs are not PDA. In America it is weird if a couple does not hold hands. Most of our politicians hold hands with their wives as a sign of togetherness and unity.
Michelle and Barack handholding:

IMHO a PDA involves kissing and making out or squeezing......to be honest Zara and her husband show more actual PDA and I remember growing up seeing Charles kissing Diana all the time. We have only seen Harry and Meghan kiss twice.
