Believe it or not, I can easily understand your desire for privacy during your enemas despite the fact that I wrote the OP in this thread about enjoying enemas with an audience. I've loved enemas recreationally and for arousal for > 50 years, but I can also understand why a great number of people find them very unpleasant and certainly not a powerful aphrodisiac. Pushing a fat nozzle or balloon or even a skinny nozzle into someone's anus and rectum and then once it's in pumping a substantial amount if water into them to fill up their rectum and then the rest of their colon making their belly swell up is not, I would imagine, most people's cup of tea! However, as expected it sounds just divine and arousing to me.
My switch ex-wife and I used to REALLY enjoy her being very Domme and giving me large, long-held enemas as her sub, and she made it even more arousing by making me include most or all of my other kinks as part of her enema treatments. We also discovered early on that her narrating and commenting on what she was doing and what she planned to do to me next, with me offering a lot of moans, groans, complaints and begging, made the whole enema even more exciting. But it was only with her and strictly confidential between the two of us. Since I trusted her and it would never leave the room, I found I truly enjoyed her doing her best to make my enemas as submissive, embarrassing and humiliating for me.
However, for several years now after our divorce, during my solo enemas now I am always fantasizing and remembering how she used to make me feel. So then I started to imagine one or more (trusted and sworn to secrecy) women friends of ours helping her give me enemas, and the addition of other women watching and helping her fill me with enema and embarrass and humiliate me turned out to be better and better, especially if they were all wearing my favorite fetish clothing which is rubber suits or clothes and sneakers. So for me and her, having several invited women friends participate with her in giving me extremely embarrassing and humiliating enemas while we were each dressed in rubber and sneakers became a common fantasy of mine (probably including tonight, I hope).
So I hope you can keep enjoying your private enemas with your husband. But if I'm ever able to find a new partner I'll have to hope she'd enjoy giving me submissive erotic enemas, and maybe even invite some of her friends to help her.
