We say “no” all the time. Sometimes we do so subtly, as a way to deny an emotion, swallow our words, or feel the disgust of “Ugh! Not that again!”
I don’t think I’m alone in this. No one likes to feel things which are uncomfortable… especially negative emotions.
Recently I was in Boca de Tomatlan, Mexico for a workshop with other clinicians and practitioners of the 4 dimensional approach to sex and intimacy. Every morning, before we would begin our work, we would clear our space. Clearing space involved using sound (a drum, a rattle, etc.), scent (copal, sage, incense, etc), or other approach to sanctify the area we would be learning and growing in to allow us to be present, to remove negative energy and to set a space that invited intention.
