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 (inner 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
Evolutionary biologists put forward several hypotheses for explaining the role of the female orgasm in terms of the reproductive process. In 1967, Desmond Morris first suggested in his pop-science book The Naked Ape that female orgasm evolved to encourage physical intimacy with a male partner and help reinforce the pair bond. Morris suggested that the relative difficulty in achieving female orgasm, in comparison to the male's, might be favourable in terms of Darwinian evolution by leading the female to select mates who bore the qualities of patience, care, imagination, intelligence and so forth, this in contradistinction to qualities such as size and aggression, which pertain to mate selection in other primates. Such advantageous qualities therby become accentuated within the species, driven by the very differences between male and female orgasm. After all, were the male to be motivated by and taken to the point of orgasm in the same way as the female, those advantageous qualities would not be needed: self-interest would do the trick.

Also, I think... when a woman has an orgasm during sexual intercourse, the contractions she has help the sperm to enter more easily. Also, it helps build a relationship between partners, as both will want to come back for more usually.
There was a really informative show on the Health Channel a long time ago, which I'm sure is still on. Perhaps you can see it some time. It definitely had an answer for most everything.

Hi. OK, I'll assume this is a legitimate question. The reason for a females contractions during orgasm is to stimulate the male into orgasm. Assuming there is a male involved, of course.

The reason is--
the juicy liquid has the chemical nature that the sperms are attracted toward it.

And to think … God made it that way just so Hugh Hefner could make millions of dollars and you could get tennis elbow. Amazing.
