Idk...the smell of old period blood is something else.
Mixed with fecal matter and urine?? They'd have to deep scrub me inside out.
Also, I don't like thought of a stranger rummaging through my vagina, to fish out a diva cup or a dissolving tampon
My plan is to empty my bowel beforehand, not drink much water and to wear an incontinence pad, to keep the mess at a minimum, and to keep it on THE OUTSIDE of my body.
