The vagina's microbiome and self-cleaning

From medieval speculums to modern myths, vaginas deserve better. Jessica Wynn takes a deep dive into these anatomical marvels here on Skeptical Sunday!

Welcome to Skeptical Sunday, a special edition of The Jordan Harbinger Show where Jordan and a guest break down a topic that you may have never thought about, open things up, and debunk common misconceptions. This time around, we're joined by writer and researcher Jessica Wynn!

On This Week's Skeptical Sunday:

• The vagina is self-cleaning with its own microbiome — douching, "pH-balancing" products, and vaginal steams disrupt this natural ecosystem and can cause infections. Most "feminine hygiene" products are marketing scams that profit from manufactured shame.
• Vaginas expand dramatically during arousal through a process called "tenting" — doubling in length and width, then returning to normal afterward. The myth that sex "stretches out" vaginas is anatomically false; vaginal muscles are elastic, not memory foam.
• Women's pain is systematically dismissed by the medical establishment — conditions like endometriosis take 7-10 years to diagnose, and menstrual cramps can rival heart attack pain. This stems from historical medical sexism, including experiments on enslaved Black women without anesthesia.
• Teaching children proper anatomical terminology is a critical safety issue — when kids know words like "vagina," "vulva," and "clitoris," they can clearly communicate if abuse occurs. Euphemisms create dangerous confusion that may protect abusers.
• Learn your anatomy and advocate for yourself — understanding your body empowers you to have better medical conversations, safer sex, and healthier relationships. Knowledge about vaginal health isn't indecent; ignorance is.
