Speaking of UTIs...
As a young teen, had one UTI and yeast infection after another. So did my sisters and mother. Mom had a number of "cures," but mostly criticisms. It was my fault. She even accused me of not being a virgin.
I should note my mom was mentally ill, super-bipolar with PTSD and OCD. She "spanked" with thin, whip-like tree branches until she raised bloody welts. But never anywhere on our bodies where they could be seen. She had 8 children and just couldn't handle it. She blamed everyone for everything because she was so fragile, she couldn't take the blame herself.
Intimate hygiene was difficult for her to teach her six daughters. She didn't even know the right words. So from the potty to Modess, it was show and tell. No words. Wipe this way.
I hope if I say back-to-front, one shot, then flush, you'll get a picture of how she taught us to spread bacteria and yeasts to fertile areas where they grew.
Every woman in my family had chronic problems and even illness and hospitalizations and surgeries related to infections from bad hygiene.
As an adult in the 1970s, with the advent of "Our Bodies, Our Selves," birth control, fun sexual techniques and experiences and a general genital renaissance for women, I learned what I'd been doing wrong. I haven't had an infection since.
Never stop learning. You may not know as much as you think you do.
