I did not know that baby powder could lead to ovarian cancer, but this does not surprise me. I am not an ABDL, but began a relationship with a guy back in June who was into the lifestyle. To understand him, I researched what I could about it and agreed to wear diapers and pee in them because it turned him on. Our first time doing it, he rubbed baby powder all over my private area and we had sex. Within days I was in considerable pain from a UTI and thought I could treat it myself with an OTC medication. It did not go away.The pain became severe with cramping in my ovaries, back and legs and I ended up having to go for emergency treatment at a medical center. The doctor said it was the worst infection of this type she had seen. Even now, many months later, I still have pain in my ovaries and lower back. So my advice is for ladies NOT to use baby powder at all, and I would be leery of it as a man as well, since there is a possibility of it entering the urethra and causing a UTI. Seriously - it's not worth it. The relationship ended recently and I am now stuck with some long-term internal damage. If you absolutely must use it, I would suggest using it only around the pubic area and not at all on genitalia.There are also talc-free powders you can use; one I like is called "Silky Underwear" by LUSH. It has a sweet, vanilla-ish scent to it, close to the scent of baby powder. I have used it in my underwear for several years and have suffered no ill effects from it.
