I enjoy an enema for its own sake and not because I 'need' it. Although, if I do need to encourage a belated BM, that naturally leads me to justify taking some personal time for myself. What really triggers the impulse to treat myself, though, is being home alone. The quiet house whispers my name and beckons me to the bathroom to dig out my gear.
I always feel I should hide the fact that I enjoy enemas, because I know no one else who does. (Except on this site, and I don't really know you.) If my husband was home, I would be embarrassed to be caught indulging myself or even staying in the bathroom too long which always brings questions. "Are you all right?"
Growing up, I got enemas from my mother whenever I was sick. Whenever I stayed home from school because I didn't feel good and stayed in bed all day, my mother would suggest an enema. She always chose the quiet time of day when my dad was at work and my siblings were in school. (Is that another reason why a quiet house still affects me the way it does?)
When my mother took me into the bathroom for an enema, I didn't always "need" it. But she didn't want to take any chances. From that time in my life I learned to enjoy an enema for what it is -- an activity with psychological aspects that brought pleasure to me. I enjoyed having an authority figure insist on giving me an enema, someone who wouldn't take no for an answer. I was trained to cooperate and obey by strict parents, so it never occurred to me to resist.
Even then, I was embarrassed that I liked getting an enema, so I would always be careful about showing any pleasure or eagerness whatsoever. She would use the bulb type and after she squeezed a few into me, she would ask, "Are you feeling full yet?" And I would be so ho-hum, "Not particularly." And she would give me some more.
I would prefer to have a partner who enjoyed enemas the way I do, but I don't, so I have to do it solo. And I have to keep it a secret due to the shyness and embarrassment issues which I've never gotten over. I know there are others who feel that this proclivity is a perversion, so I'm not alone. To me, having an enema is a fun thing to do and rarely stems from any health-related motive.
