text: anal douche? can douching cause damage, if so how and how do you prevent it. what are the benefits of douching. thanks. anything you do wrong can cause damage. follow the instructions on the container and dont over do it. and do not make a habit of having an enema. your body can end up dependant upon the process and you wont be able to excreete feces without having an enema. im not kidding. these things arent meant to be used on a reg basis.
