well there r 2 orgasms male and female
the male one
In a human male orgasm, there are rapid, rhythmic contractions of the prostate, urethra and the muscles at the base of the penis, which (in the adult) typically forces stored semen to be expelled through the penis' urethral opening, in a process known as peristalsis. This is referred to as ejaculation. The process generally takes from 3 to 10 seconds and is usually extremely pleasurable.
Orgasm is generally induced by direct stimulation of the penis. Some men experience heightened orgasm by direct stimulation of the prostate through the perineum or rectum.
As a man ages, it is normal for the amount of ejaculate to diminish, and hence, the length of time the man sustains orgasm also diminishes somewhat. This does not affect the pleasurable feeling of orgasm at all, it merely shortens the duration of it.
Following ejaculation, a refractory period usually occurs during which a man cannot have another orgasm. This period can be anywhere from less than a minute to over half a day, depending on age and other individual factors. A few cases have been reported of men who appear to have no refractory period at all
the female one
In a human female orgasm, orgasm is preceded by moistening of the vaginal walls, and an enlargement of the clitoris due to increased blood flow trapped in the clitoris's spongy tissue. Some women exhibit a sex flush, a reddening of the skin over much of the body due to increased blood flow to the skin. As a woman comes closer to having an orgasm, the clitoris moves inward under the clitoral hood, and the labia minora (minor lips) become darker. As orgasm becomes imminent, the vagina decreases in size by about 30% and also becomes congested from engorged soft tissue. The uterus then experiences muscular contractions. A woman experiences full orgasm when her uterus, vagina and pelvic muscles undergo a series of rhythmic contractions. The majority of women consider these contractions to be very pleasurable, although not all sexually active women experience this.
After the orgasm is over, the clitoris re-emerges from under the clitoral hood, and returns to its normal size in less than 10 minutes. Unlike men, women either do not have a refractory period or have a very short one and thus can experience a second orgasm soon after the first; some women can even follow this with additional consecutive orgasms. This is known as having multiple orgasms. After the initial orgasm, subsequent climaxes may be stronger or more pleasurable as the stimulation accumulates. Research shows that about 13% of women experience multiple orgasms; a larger number may be able to experience this with the proper stimulation (such as a vibrator) and frame of mind. However, some women's clitorises and nipples are very sensitive after orgasm, making additional stimulation initially painful. It is possible to engage in deep, rapid breaths while continuing stimulation and making a conscious intention to release the pain and tension. Doing this can allow for the intense stimulation to be interpreted not as painful but as intensely pleasurable
multiple ones in females
Achieving multiple orgasm
Some women can achieve multiple orgasms: a series of orgasms, one after another with possibly increased intensity after the first. The great exertion involved can be blissfully debilitating for quite some time after.
This kind of orgasm would normally involve stimulation of the woman's clitoris rather than the vagina. Some women can do this manually using their fingers taking a pause of two or three seconds between each. When using their hands, women can insert fingers up the vagina, wriggling their fingers to stimulate the G-spot, also the women may also massage the clitoris repeatedly.
A vibrator applied directly to the clitoris can enable women who are not practiced in using their fingertips. A vibrator used this way can be applied almost continuously to bring about orgasms that seem less separated. A battery powered tooth brush that vibrates with an oscillatory rotational motion is preferred by some for whom it is more effective than a vibrator
