Observing your partner during an enema

Hi! Hope everyone is doing well and had a wonderful holiday! This topic may have been discussed before, but I couldn't find the answer. This question is probably aimed at heterosexual men. Have you ever watched your girlfriend, wife, or lover give themselves an enema and just watched? Or maybe you participated in some way? For example, by inserting a large amount of liquid into the enema. What sounds did your partner make? What sensations did you experience? Do you prefer to be a passive observer or actively participate in the process? How did you feel when your partner began to moan with spasms? Did you want to stop the procedure or, conversely, continue?
