I do not really recall my first enema...but it was before I was 4, so late 40's. My older sister got them, too, and those first enemas were only when we were sick. When I was 8, we moved in with my maternal grandmother, and things changed! First of all, Sis & I got a dose of Fletcher's Castoria every night at bedtime. If we didn't get a good BM first thing (Yes, she checked) then we got a suppository, which we had to hold while eating breakfast. If we still didn't get one before time for school, the unlucky sib was kept home for enemas. Regardless of other enemas, Wednesday after dinner and Saturday morning were enema times. I should mention that enemas and supositories were talked about openly...Mom & Grandma gave to each other, although Grandma usually gave to Susan & I. Enemas were given in Grandma's main bathroom, which was large, and had a huge clawfooted bathtub square in its center. An oval track of pipe was suspended from the ceiling above for the shower curtain. Sis and I were always given our enemas together, and were totally naked. Until we were tall enough, we knelt on footstools bending over the tub side, palms flat on the floor. As we grew taller, the footstools were not needed. Our bags hung from the shower rod above us. We grew up in a household where nudity was not frowned upon, so we never gave it a thought. (That, and our minds were busy with the warm soapy water filling us,) Once we finished our bag, there was a holding time, which eventually became 30 minutes. Once our enemas had churned long enough, Sis got the toilet in the main bath, and I ran for the guest bath to gain welcome relief. Wednesday night was one SSE, and one rinse. Saturday mornings actually started Friday night, when we were given 2 tbsps of castor oil at bedtime, and diapered, just in case. Not infrequently, one or the other of us woke up with a dirty diaper. Grandma cleaned us up until Sis was 14, when she was given the task of cleaning herself, and/or me. Soon, I was cleaning myself. Dirty diaper or not, we both had to get a BM before breakfast, and sometimes that meant supplementing our laxative with a suppository or two. Once we finished dumping, we got breakfast. Then, all four of us, Grandma & Mom included, started a series of enemas til clear, This usually involved 3-4 SSE's followed by 1-2 plain rinses. Sis & I started getting 1/4 a bag (4 qt bag, common in the forties), but by the time we reached adult size, we were getting a laddered series: 2 qts, then 3, finally the whole bag. (One memory that stands out was my sister's first enema on her period. As the 4 qt enema filled her, the pressure against her uterus/vagina caused her to bleed a puddle.) I had no idea what was happening, but Mom reassured her that it was OK. If all went well, Sis and I were rewarded with tickets to the Kiddie show Saturday afternoon, with money for popcorn, drinks, and candy.
When Sis was about 17, she surprised me one day when Mom & Grandma were out for the day. "Do you ever kind of want an enema? I do. Want to give to each other?" I was surprised, but actually HAD been realizing I looked forward to getting mine. I agreed, and soon we were naked, mixing up our soapy water, and kneeling while our bags filled us. This was such fun that we started doing it any time we had enough time. Sometimes, after Sis got her license, we would sneak our bags out and go to a wooded area outside town for enema contests...who could take the most, who could shoot our expulsion the farthest. This was a rare event, but we did it 5 or 6 times over two years, until Sis left for college. We married, and moved away, but any time we visited each other, we would find an excuse to take four or five hours "shopping"...at a no-tell motel, for enemas. No, we never had sex! We're both widowed now, so we visit frequently. The only downside to our enema rearing is that we both developed chronic constipation, and cannot get a BM without help from a laxative, suppositories or enemas. Did I say "DOWNSIDE"? Nah!
