Does this make sense?

First let me assure you that my wife is absolutely uninterested in sex, and absolutely disgusted at the thought of any anal activities. Now for the reason for my post. I'd love to have the opportunity to spend several hours enjoying enemas and the wonderful feelings of anticipation and preparation and lubrication and insertion and distention and evacuation and relaxation. Whew! Seriously, there is a psychologically therapeutic benefit to a thoroughly complete enema workout, and my innards are longing to experience the flow of very warm ivory soapiness flowing into my colon. Reader alert: I love the feeling of slick cecum evacuations which tell me that the enema has been successful. At that time, the smells also say "success". For me, the result of a great enema session (other than the sexual one) is that it will be two days before I will have a bowel movement, and that keeps reminding me of the enemas that were so much fun and felt so good. The enema session provides a feeling of sexual satisfaction that lasts several days.

Yup! An enema session is very sexual for me, in all respects. On the other hand, wife is interested in sex though not my enema fetish. She knows I;m very anal and gives me lots of satisfaction that way.

I think I would try asexual enemas, Sooner or later, an enema orgasm happens a teachable moment occurs. Jump at the opportunity.
