Describe the physical feeling of being in love, please?

Something bursting out of your chest? A warmth overtakes your body? What?

For me, when I’m with my SO and we’re physically close (I’m holding her), it’s feels like (sounds corny, I know) a large beam of something shooting out of my chest and into hers and it holds us there. Also, my whole body is tingly. She feels the same way.
