And if you do it anyway... what, exactly? If you're only really interacting with your loved one and close friends, do you honestly stand to actualy loose anything at all? Perhaps if couples were a little more open with affection in Japan, love would naturally begin to flourish more easily there.
		
		
	 
if you do it anyway,.it like shouting and swearing like drunk in fine dining. someone will look you with side eyes.
love didn't need to be show off to be strong. just you open with affection, doesn't meant its more flourishes. Divorce and break up cases are more prevalent on non PDA countries. actually is more good to hold it back,.only to unleash it all at home with your spouses so the love feel more special. going home together, enjoy bath together is what you wait the most. it become a moment exclusive between you and your partner. not for everyone else.
after all, water taste more refreshing after you work out. same goes for love. you don't need to show off your love on public to make it feel more natural or begin or anything. its make you more appreciate the every moment of love making and affection gesture between you and your partner. it deepen you love more. 
did i mention jealousy? yeah, someone might get jealous with you and tried to ruin your relationship. During 70-80, people didn't show much affection on public but the marriage last long and relationship were more stable and strong. today people show off more on outside but relationship didn't last that long. even good steak taste bland if you eat ate it every day. by limiting it,.make you appreciate more, enjoy it better.
