Physical touch goes way beyond intimacy. Holding hands, cuddling, random hugs - these small touches build and maintain connection in ways words can't.
I've been in relationships where the touching stopped once the "new relationship energy" faded. It felt like we were just roommates sometimes. Making an effort to maintain physical affection makes a huge difference.
Love Languages
If your love language is physical touch, you need more than just occasional intimacy. You need consistent, casual touch throughout the day. Communicate this to your partner if they naturally show love in different ways.
