Growing up, mom and her two younger sisters, used enemas and douched during their period each month. Mom, unlike her two sisters, didn't care for enemas. So, she douched, more than she used enemas.
As preteens, our RN grandmother taught me and my siblings to give ourselves enemas, and our sister to douche. Like my sister, my wife started douching and giving herself enemas as a teenager, on the advice of her OB/GYN.
The year before my wife and I got married; she and my sister shared an apartment together. Up until that point, she only douched during her period, and used enemas as warranted for health issues. The year they shared an apartment, out of continence, they started swapping enemas with one another. During those enemas, like most girls, they talked. My sister, telling her about our after-school activities, as teenagers. Plus, she learned the pleasurable side effects, of being given an enema using a long-curved douche nozzle. Along with, how to use it, when she gave someone enema.
The following year, after we were married, my wife and I use enemas for health and pleasure on a regular basis. Shortly afterwards, like my sister, she starting asking me to help her douche, whenever we took a shower together.
I can say this much about it. My mom, aunts, sister, girlfriend, girlfriend's sister, and wife. All benefited from enemas and douching, before, during, and after their periods. Definitely taking care of their needs, when they had issues with constipation or period cramps.
