Vagina - What is it?
VAGINA
The vagina is an elastic and muscular canal, which has a soft lining that is flexible and provides lubrication and sensation.
The uterus is connected to the outside world through the vagina. The vulva and labia form the entrance and the the cervix of the uterus protrudes in to the vagina forming the interior end. The vagina serves as a conduit for menstrual flow from the uterus which is also where a penis is inserted during sexual intercourse.
The hymen is a thin membrane of tissue that surrounds and narrows the vaginal opening. The hymen can be torn or ruptured by exercise, tampons or sexual activity. The G-spot was named after a German doctor chairman Ernst Grafenberg who first wrote about erogenous zone in the anterior vaginal wall.
The region behind the pubic bone is often credited as the trigger of vaginal orgasm and a catalyst for female ejaculation. Whether that is the isn't a g spot depends upon whom you ask. No gynae surgeon has seen a g-spot during an operation. Menstruation refers to a females monthly bleeding.
When a female menstruates her body sheds the lining of the uterus or womb. The menstrual blood flows from the uterus through a small opening in the cervix and exits the body through the vagina. The average menstrual period is 3 to 5 days. In the united states an average girl will receive her period when she is twelve years old. Normal ages for the start of her period are eight to fifteen. Most often the first period starts about two years after the beginning of breast development. A few days before the start of menstrual period most women experience tender breasts, bloating and muscle aches. These are normal premenstrual symptoms. Once these symptoms begin to affect a person's daily life, they are referred to as Premenstrual Syndrome or PMS. PMS may affect a person's body as well as their mood.
Some women experience their first PMS in their teens or 20s. Some do not experience PMS until their 30s. The symptoms may get worse as a female approaches perimenopause. While there is no such thing as male PMS, males can experience their own version of a hormonal change. IMS or Irritable Male Syndrome is a condition that men suffer from and is characterized by irritability, mood swings, hot flashes and even stomach cramps.
IMS is not monthly but can happen at any time since it is caused by a drop in levels of the hormone testosterone. Painful intercourse affects about 60% of women at some point in their life.
While many factors might come in to play, this pain can be caused due to the penis hitting the cervix. This is common when a male's penis is longer than the depth of a female's vagina. Narrated by Erica Laba, Animated by Andrej Preston Concept Art by Lindsey Millikan.
