1.
The vagina is a muscular barrel about 3-4 inches long,
in its non-aroused state, lined with mucous membranes, similar
to the lining of the mouth.
2. The vagina is angled upward at around a 65 degree angle,
which very closely corresponds to the angle of the average erect
penis.
3. The vagina isnt a wide-open gaping hole. Its
a collapsed space that expands and contracts when excited or penetrated.
When in a non-aroused and un-penetrated state, the walls of the
vagina collapse against each other, sort of like a firehose.
4. The vaginal lining is pink and glistening and has folds,
called rugae, which give the vagina a ribbed texture. These folds
are much more pronounced in younger women and gradually disappear
as a woman grows older.
5. The vagina stretches out when the lady gets excited.
The cervix and uterus pull up and back, extending the vagina by
about 1-3 inches. The back of the vagina balloons out to create
more space.
6. 2/3 of the nerve endings in the vagina are located in
the first 1/3 of the vagina.
7.
The first 2 inches of the vagina are the tightest during intercourse,
due to the vaginal swelling and engorgement of blood.
8.
Vaginas of sexually mature women are elastic enough to accommodate
nearly any sized penis.
9. Around 1 in 5000 women is born with a disorder called
vaginal agenesis, in which they are born without a vagina, in
spite of the presence of external genitalia, such as labia and
a clitoris.
10. Shortly after stimulation, the vagina begins to lubricate,
forming what looks like beads of sweat all over the vaginal walls.
