Now I know, if you are in a relationship, you're probably wondering exactly what acceptable forms of PDA there are, that won't drive your single friends completely bonkers. I've been in a relationship for about 6 years now and I actually had all of my single friends come up with this list of acceptable forms of PDA that won't drive them nuts when we all hang out. I know it's hard show affection to your partner when you are in public, but girls, let's keep it all simple!
Of course hugging would be on the acceptable forms of PDA list! This is a traditional form of PDA that even friends use, so if you want to hug your partner in public, do it! Nobody should ever have a problem with hugging and if they do, are they really your friends and happy that you are in a relationship?
