My Father raised me as a single parent!
Once I turned 12, he encouraged me to self-administer, but told me to take them only when he was home, and leave both the bedroom and the bathroom door open so that he could hear what was going on, and could come to my aid if I called him, or if there was an obvious problem.
His own Mom was, and still is totally against enemas, at least for boys, and he came from an all-boy family! So he had to take all his enemas behind his mother's back, and sneak Fleet Enemas, Epsom Salt, Magnesium Citrate and eventually a bag into the house without her knowledge, and take enemas when she wasn't going to be home for a while. He had a younger brother, so he pretty much had to hide it from him as well, because he would get ratted out! He was lucky, his Father was something of a bookworm. He would take my Dad to the library, intending to watch him, get engrossed in his reading, and totally ignore him, and he could read anything he wanted!
He told me when I was 10 that as he was leaving court after getting permanent custody, he made a solemn vow to himself that, if I ever decided I liked enemas, or other "Off mainstream" behavior, I was not going to hide it from him, we would be as open with each other as possible!
He took his own enemas only when I was in school until I was 18, but he never lied to me about when he took them. He said the first time the subject of enemas came up, "There are certain things that a kid should learn form parents! I will make sure that I am the parent YOU NEED, rather than the parent I'm ready to be! So no, we were always totally open about them! He even told me once, when I was in High School,
"f two enema lovers hadn't found each other, you wouldn't even exist, so why should either of us deny who you are!"
