There is a specific flavor of bad information that some men carry around about women's bodies, and a recent viral thread surfaced the worst of it. Development executive Sabrina Fonfeder kicked off the tweet with her own ex, who apparently believed every woman got her period on the 15th of the month. The replies got weirder from there.
This is the kind of story that makes you laugh and wince at the same time.
The short version
- Sabrina Fonfeder, a development executive, posted a tweet about her ex's misconceptions about women's bodies.
- The example given was a man who believed every woman got her period on the 15th of the month.
- The tweet went viral and other women added their own horror stories.
- Bored Panda interviewed Fonfeder, who framed the issue as one of education, not individual ignorance.
- The thread is a useful snapshot of how little biology some men have been taught about women.
What Fonfeder said
Fonfeder told Bored Panda that the problem is structural, not personal. Men are not taught much about women's bodies because women are framed as beautiful specimens, she said. Get rid of body hair. Periods are gross. Pregnancy and labor are not taught until a woman goes through them herself. The shame around existing as a woman keeps these conversations quiet.
That framing matters because it moves the conversation from "look at this idiot" to "look at what we are not teaching." The former is a roast. The latter is a diagnosis.
What it means for you
Say you are dating someone who says something confidently wrong about how bodies work. The right move is to correct gently, not to mock. Mocking shuts down the conversation. Correcting opens it.
Better move: ask what they were taught. Most of the myths come from bad sex ed, not malice. The conversation is more productive when you treat it as a curriculum gap.
Why this matters
These threads matter because they normalize the conversation. For readers who grew up being told not to discuss bodies in public, the thread is permission. It also does something useful for the men who read it: it gives them a list of myths to check their own assumptions against.
What to watch next: more body-literacy content. Sex education is uneven across the U.S., and the gap keeps producing viral threads. Expect more.
Bottom line
The myths are funny until you remember they are still being taught. The fix is education, not embarrassment.
Key takeaways
- The viral thread started with Fonfeder's example of an ex who thought all women got their periods on the 15th.
- Fonfeder framed the issue as a curriculum gap, not individual ignorance.
- Correcting myths gently works better than mocking, which shuts down the conversation.
- Sex education gaps in the U.S. Keep producing these viral reveal threads.
