Females anal passage does it widen naturally ?

I can para phrase a teacher from when in school . He said " the expression broad when in reference to a female comes from the following. They have wider hips for giving birth."

Is it the similar for women and anal sex ? Does that passage widen in its own to accomodate different penis lengths and girths ? Or only thru experience does it widen ?

The pelvic inlet and outlet are wider for giving birth, which at "full dialation" is around/nominally 10 cm diamater, or on average 34 cm in circumference. As much as guys may dream and wish and pad numbers the human penis is not even close, studies I have seen show a range up to about 15 cm erect circumference in ordinary population studies, less than half the size. While this is bigger than what is considered ordinary and ideal stool size, it is not anywhere near the size where the wider pelvis would make any difference. The anus widens through relaxation of the sphincters, and most people can probably take about the same size of toy whether you are M or F until it gets up in the "oh wow" size range.

Wide hips allow the babies head to pass through the pelvic bones during birth. Wider hips doesn't make the vagina, a stretchy muscular canal, larger. Likewise the anal sphincter is a muscle that can can stretch to allow bowel passage, and can gradually be strectched to accomodate larger objects.

"Broad" reference to women may also have derived from the term “abroadwife”: a term for a slave woman, or just a woman who was separated from her husband. The word “broad” in the 18thcentury meant a wide playing card, which were often used while riding the trains. Train "tickets" were similar to the cards and a "broad" became a slang term for a ticket and eventually for a pimp's "meal ticket", e.g. a prostitute,

I have had a very large dick, a woman's arm almost to the elbow, and several large plugs. Yes, it expands.

@Rigel ,

I enjoy tidbits like that. Thank you for the information!

The colon is a muscle and muscle do have some give and take. So there is some ability to stretch to accommodate for different sizes...diameter and length.

Too much of a size difference though may need some time and patience to get the anal sphincter to open for the diameter. One should not rush to insert if there is resistance so as not to damage the sensitive tissues in that area. The use of lube will also help to make the experience more pleasurable as well.

Checking with GPT4:

The term "broad" as a slang term for a woman originated in the United States in the early 20th century. The exact origin of the term is not known for certain, but there are a few theories.

One theory is that the term "broad" originally referred to a woman's hips, which are broader than a man's. Another theory is that it originated from the term "broad-minded," which meant someone who was open to new ideas and experiences, and was later shortened to simply "broad."

The term was originally used as a derogatory term to refer to women, particularly those who were considered promiscuous or sexually liberated. However, over time, the term became more widely used as a slang term for a woman in general, regardless of her behavior or reputation.

I think that part of human anatomy works pretty much same for both genders.

And yes, it can stretch a lot, female and male.
