To be honest, 'adapting it' is just being myself. I'm from a place that does the same - physical affection is just not common back home, even myself or my friends do it sometimes.
It's definitely a huge form of 'culture shock' even if I'm personally aware that other countries back home do a lot of physical affection.
In the end, adapting to that sort of thing was more or less 'act the way you want to' over 'what society wants you to act'. Do what you want to do rather than just copying what everyone else is doing. It's not like anybody's trying to shove it down your throat. Although if they are handing out weird shit, you probably should tell them (politely or otherwise) that's not the kind of crap you're into. Or just don't take them.
