Im all for the enima idea...Im a straight male, no anal, and i still do it from time to time. Not only does it have a friendly tickle, but it makes you feel nice and clean. You dont have to use something that penetrates into you, a simple squeezable plastic bottle such as a well cleaned water bottle or shampoo bottle does the trick. Just place it up against the exit and squeeze and the water magically makes its way in...Its a good idea to be prepared for a bit of a mess, i suggest doing this near the toilet instead of all inside the bathtub
