Sunny,
What you are daydreaming of is surgically possible.
I do not know of a surgeon who would do it, though. I will not be so presumptuous and condescending to recommend therapy, but before a reputable surgeon would entertain doing this, therapy would be required.
It has been my experience that lot of women are becoming chronicallly infected with Chlamydia, or other Chlamydia-like infection and are not being properly treated for it. The problem being that the female reproductive system, unlike the male reproductive system, is open into the peritoneum. I know that this is probably a lot of medical mumbo-jumbo to you but please bear with me.
In a female, the infection enters into vagina, goes into the uterus and thne into the abdomen through the fallopian tubes. It chronically infects lower regions of the pelvis that results in constant, chronic pain. If left untreated scarring of the fallopian tubes renders one sterile and the area called the cul-de-sac, a fold of peritoneum between the uterus and the rectum, fills with infected fluid and makes life a living hell of constant, chronic, crampy pain. The treatment is I.V. therapy with a strong broad-spectrum anti-biotic such as Flagil and lots of bed rest. For chronic cases, flair-ups are common and as long as they are treated in the manner that I described and as long as the chlamydia or whatever does not develop an immunity to the antibiotic the condition can be put into remission and probably cured, if the woman does not get herself re-infected. Usually, it has been my expereince that re-infections occurs from an chronically infected male, or a promiscuous one, or some combination of the two. Generally, males are spared most symptoms that I described except for a chronic pus-like discharge out of the urethra that comes and goes. Usually, they have no pain and are without significant symptoms. Some of the bastards refuse to see the doctor or to abstain from sexual relations until they are non-contagious. These are the ones that need de-sexed, not the women.
So, as a woman experiences these things, she is likely to want it all cut out out of frustration. I am sure that may not be a good alternative. Untreated, this condition usually results in a lot of misery and finally the need for a hysterectomy, usually vaginal, that results in the vagina being left a blind pouch, sealed off from the internal abdomen. Sometimes part of the cervix remains but if so, it is sealed.
In such a surgical procedure the uterus and vagina are prolapsed externally and the blood supply is ligated and then the vagina sewn shut and anchored back into the proper place in the pelvis. It would be a simple thing at that point to do what you ask, but a surgeon would not do it out of fear of a woman changing her mind and suing later. Also, a husband, or I suppose a lover of long standing, could sue the surgeon for causing the loss of a sexual partner.
Other medical conditions that cause the female misery include prolapse of the uterus that produces much the same symptoms, i.e., chronic pain. The brutal act becoming more and more popular among the kinky that is commonly known as "fisting", in a female, usually results in the tearing of the muscles of the vaginal wall and causes rectoceles and cystoceles. Formerly, these were injuries sustained only during vaginal delivery of a big baby or after several births, and a woman under 30 rarely had them. Now, women in their 20's are showing up with these problems. These conditions are herniations of the rectum and the urinary bladder, respectively, into the vaginal canal. This causes incontinece under stress such as happens from sneezing, jumping rope, or jogging. You leak pee into your pants. Rectoceles, if bad enough, cause the need to digitally manipulate the vaginal wall to properly deficate and to clear the rectum of fecal material. (You have to push your poop out with your finger.)
Now, Let me tell you that all of the conditions that I just described are, usually, surgically correctable. Hysterectomy usually results in early menopause, and sexual need diminishes significantly, even if the ovaries are left.
If what you want is an erotic dream, perhaps it is best left that way. If you are experiencing any of the symptoms or conditions that I have outlined, see a reputable gyneocologist in a teaching medical center. Such a place is where doctors are trained and so will have the best doctors that you can find to put your bottom together properly.
At any rate, if you are having medical problems that are causing you to want your sex cut out, first try getting it fixed so that it is reasonably normal and then try living with it that way after the repair surgery for at least two years before you pursue having anything done that would remove your ability to have sex should you choose to do so.
I will tell you the same thing that I tell everyone else. Once you have it cut out, it will never grow back and it will be gone forever. This is something that is irreversable. I hate to see anybody do this, but for some strange reason, it bothers me more when females want it than when males want it.
