G-spot orgasms are different from clitoral orgasms, in that the cervix pushes down into the vagina. By stimulating the G-spot, through touching, rubbing, or penetration - it is often recommended to use a come hither motion with your fingers - the nerve endings in the urethra are put on high alert and become extremely sensitive. Up to 50% of women who experience G-spot orgasms may also experience female ejaculation during orgasm.
While orgasms themselves can be different for every woman, the physiological responses
of the body are similar. When a woman first becomes excited, the blood vessels within her genitals dilate and the vulva swells and becomes wet. When the blood flow to the lower area of the vagina reaches its limits, the vagina becomes firm and the clitoris can "disappear" by pulling back against the pubic bone.
When a woman reaches orgasm, her body's genital muscles experience contractions just less than a second apart, lasting anywhere from 13 - 51 seconds. This is when a woman may expel one of three fluids - urine, a urine-like substance, or female ejaculate.
The release of urine is often the result of urinary incontinence. The urine is sterile and harmless. Strong muscle contractions during orgasm may also cause "squirting", which is the leakage of the urine-like substance. The watered-down milk looking fluid is female ejaculate, and is most often produced during G-spot orgasms. This fluid has been analyzed and found to resemble male prostate excretions.
Once a woman has orgasmed, her body returns to normal, the swelling goes down, and she rarely needs any recovery time. If stimulated again, a female will be able to experience another orgasm.
