"Most porn improperly validates these concerns because everyone in porn is impeccably clean. "Analysis:
If one is forced to prepare for sex so extensively - might it be providing some intrinsic information back to the two (or more) participants as to the actual function of that particular orifice?
The reason many of us are concerned about anal cleansing is because of being dirty. We were conditioned from a young age to be embarrassed about it. Just look at the expression of someone changing a baby's diaper sometime - ever think that those feelings get transferred to the baby? Of course they do! Many of us still carry some trauma from these experiences. This is a natural bodily function and is nothing to be embarrassed about. Besides all the cleaning you do will be private - no one else needs to be with you to clean yourself out.
I don't recommend using laxatives to help clean your digestive tract. Laxatives can cause dehydration and their regular use can be harmful to your digestive system.
You'll be using water to clean out. Be sure to pay attention to the temperature of the water you use. The nerves inside the rectum are designed to sense pressure (when you feel this pressure you note that you need to go to the bathroom.) These nerves don't sense temperature very well, so you could harm yourself by using hot water. Cold water won't hurt you but can give some men cramps. Be sure to check the temperature of the water before you insert it. I recommend the "baby bottle" test. Splash a bit on the inside of your wrist - just like testing a baby's bottle. The water should be comfortably lukewarm on the inside of your wrist.
