PDA is not everyone’s forte and it is not compulsory either but it is good to express love for your partner, publicly, in some or the other way. These two sometimes snuggle, kiss or hug besides saying it out in words. If you find it awkward when it comes to physical distance, you can always express it sometimes in a few words that you love your spouse. These small things count a lot in a relationship. It works on eliminating any kind of insecurity your partner may have regarding your relationship as well.
