To clarify for the OP:

The orgasm, in either sex, can be broken down into four stages (thanks to Masters and Johnson) called the sexual response cycle: excitement, plateau, orgasm, and resolution. During excitement, many physiological changes take place in both sexes. In females, the breasts enlarge and nipples swell, vasocongestion leads to excretion of fluid from the vaginal walls, and the uterus moves higher up into the abdominal cavity, lengthening the vagina somewhat. The clitoris and other sex organs such as the labia begin to swell. In plateau, the Bartholin glands produce fluid, the clitoris continues to swell but withdraws a smidge under its hood, and the labia continue to swell.

Orgasm in females results in very pleasurable muscle contractions in the pelvic region. All of the muscles one uses in doing Kegel exercises begin to clench reflexively, and the uterus also contracts. In most females, this group of contractions can last anywhere from 15-30 seconds--sometimes longer. I can make an self-induced orgasm last as long as 45 seconds, but my g-spot orgasms are usually only about 15 seconds long (they are, however, much more rapid in coming).

Some women have the great fortune of having more ways to reach orgasm than others--some can come via breast stimulation, having their thighs stroked the right way--but only about 25% of women actually orgasm from traditional vaginal intercourse. Personally, during traditional intercourse, I'm more likely to come from his penis repeatedly hitting my cul-de-sac (the posterior fornix) and bumping my uterus. I can also come from being spanked if the spanks jar my uterus. Like I said--there are a variety of ways for women to reach orgasm, and we're all different. I can also come from having my back stroked a certain way after sex--the great beauty of being multi-orgasmic (women usually spend a couple of minutes in the plateau phase after orgasm, instead of going straight to resolution, like the majority of men do).

Given what you've said, it's more likely you're just hitting the excitement phase. Some of the sensations in excitement/plateau can feel like mini-orgasms...but like ng said, if you've really had an orgasm, you don't have to ask.
