My hubby and l have used mineral oil enemas for quite some time. Not really sure how we started for sure. Maybe just saw the Fleet mineral oil, tried them prior to anal sex for extra lube or a colon tube. But we always use mineral oil. Sometimes in a bulb, sometimes in a bag or have even used a large capacity syringe on occasion for something different. But we were talking the other night after he flooded me with 2 bottles of it and a colon tube, if others used only the pharmaceutical grade mineral oil or have others used light cooking oil without issue?
I do have to admit the experience of holding that much oil and moving around did create some very different feelings over water. Especially turning from hands and knees, shoulders down, then flipping over onto my back and feeling the weight of it was impressive!!!
