I’m always impressed at how when I close my eyes, my body re-syncs itself automatically.
It immediately gets my nose to reach out for more oxygen. To breathe deeper.
Slowly, muscles relax and reach a comfortable position. Usually with limbs along the body.
If I’m eating with my eyes closed, my body starts slowing the process down. I masticate longer and swallow less air with each bite. Just automatically.
I think kisses are so much more enjoyable to give or receive with your eyes closed. It becomes a moment rather than a thing to do.
