Hugging/holding, what's going through my mind is this is great. The hugging will end momentarily, but the holding I think I feel so comfortable, I think this girl likes me or she wouldn't be letting me hold her which makes me feel good, I enjoy the feeling of the skin on skin contact, and if it's a cold night the warmth of our bodies, I I think about how enjoyable it is. For the looking part I usually think wow, she's hot/pretty/beautiful.
If its someone really special to me, my heart pounds, and it feels like I'm in heaven. Its like a moment you don't want to end, or a feeling that you would love to have everyday for the rest of your life
