Always when I need one. It could be because I have been a bit constipated or perhaps a diet that I know will tighten my guts. Then there is the sexual need. I get those urges that tell me I want anal play. Even thinking enema causes my penis to get stiff. I really don't want a homosexual relationship, but I do enjoy anal penetration. I would really enjoy an evening of anal play with a willing woman. I have been there before, and loved it. The one thing is, I know a clean, fully functional bowel is essential to good health. I try to have a good diet, I try to exercise as I should, but this does not guarantee optimal health. Quite honestly, keeping the poop moving is a vital requirement for this. Enemas, yes, laxatives, no! I thoroughly hate taking chemicals to provide a bowel movement. I know that for me, soapy water into the bowel moves things a lot better than chemicals. Plus I get to enjoy slipping something into my rectum that feels good. Being an E-fan also allows me to practice my particular fetish that I really, really enjoy. The bag, or bulb, the nozzle or tube, the soap or coffee, plain water, etc. I am an enema freak. This is also why I enjoy Zity so much. The members of this site have liberated me in so many ways. I have a collection of bags and bulbs with nozzles, tubes, pumps, clamps, hangers, shutoffs, adapters, oh, oh, oh ..................! You all know what I mean!!!! Thank you all once again for sharing. Be good to yourselves, and do what feels good to you. MRay.
