I am the wife who would have liked my husband to become interested in enemas and all things anal. however my deep shame of my own interest prevented me from admitting even to myself that rectal and anal activties, certainly enemas were legitamate forms of pleasure.
My husband was actually quite adventurous and for some time had been playing with my anus and sometime inserted a vibrator which I did very much enjoy. This led to experimenting with anal sex which I enjoyed far more than I was free to tell him.
I had also discovered the hand held shower for orgasmic relief and would often fill myself at the same time by removing the head and aiming the jet at my anus as as prelude to orgasm,(when he wasn't home)and often started the orgasm before I had finished releasing the enema which together are both highly erotic.
My husband knew i enjoyed the shower spray for orgasms and bought me a douche bulb which I consequently used for enemas. 'A gift from the 'enema' god
I realize now I had many opportunities to lead on and 'wonder' what it would be like to have water in the rectum as well.
Eventually the current craze for colonics made it much easier to bring up the subject and I was discovered having an enema for 'health' reasons, and it was. It was very easy to add that it was very pleasurable sensation which my husband was very agreeable too. A very intimate discussion followed as I admitted how I was afraid he would think badly of me. To the contrary, he willingly agreed to give me an enema at the next available opportunity.
For many reasons we never quite got around to it, but he did start to experiment having them himself but was not quite ready for me to be directly involved.
I do understand the position of those who don't want them as I had the same problem with oral sex. I don't think it is bad or wrong. Just not appealing to me and actually makes me feel nauseous at the thought. However I allowed my husband to try it on me, and it was really a non event,nothing happened. Maybe because I could not imagine anyone enjoying it.
So my encouragement is that those of you who don't' have a partner who can join you on this, there are many ways to approach this subject, and you will not always have success, but it is better to try and fail, than to never try at all.
You never know what the response will be, and who knows, there may even be occasions when your partner is more receptive than you think, but not able to accept there own interest.
A good example of this was when my husband went to the Dr office and read a magazine while waiting. There was an article on colonics and talked about Princess Diana being a fan of them. He came home and jokingly suggested that he give me an enema, but instead I put him off like I thought it was disgusting!! And wished ever after that I had taken him up on it.
Expectation is a desire killer and the more gentle your approach the better.
I wish i could say that my ideas are foolproof, but unfortunately they are not, and know for myself that it highly unlikely unless I have extreme change in desire for me to put my mouth on any mans penis, at any time much less when they are about to have an orgasm, just writing about it does bad things to my stomach.
Yet it is a mystery to myself that I love enemas, suppositories and anything in my anus. Hope this helps someone.
