Can you show affection in public?

Hands, yes. Lips, no — and that applies to everyone, married, unmarried, or celebrating an anniversary. The public sphere here is modest by common consent, and the rules press harder on Moroccans than they ever will on you. A couple holding hands or walking arm in arm draws no attention in the cities. A kiss in the street draws exactly the kind you don't want — usually just stares, in principle a public-indecency complaint, though for visitors it rarely travels past disapproval.

The confusing part is that Morocco is enormously physical — just not romantically, not in public. Men greet with kisses on the cheek, women walk entwined, friends drape over each other in cafés for hours. The line was never touch; it's romance made public. And it ends at the riad door. The courtyard wall is where the public sphere stops — which is, historically, precisely what it was built to do.
