I have found a few studies that provide some numbers for the average
number of premarital sexual partners for women in the United States. A
few other studies mention the "total" number of sexual partners during
a women's lifetime, which doesn't imply stricly premarital
relationships, but still provides a good general reference.
In your clarification, you did say "I just want to find ANY study
that suggests how many DIFFERENT sex partners they have before
Here is what I have found:
This first study is the most concrete, but is dated!
From "Current Trends Premarital Sexual Experience Among Adolescent
Women -- United States, 1970-1988." January 04, 1991 /
"In 1988, adolescents who had had sexual intercourse earlier in life
reported greater numbers of sex partners.
* Among 15- to 24-year-olds who initiated sexual intercourse before
age 18, 75% reported having had two or more partners, and 45% reported
having had four or more partners;
* among those who became sexually active after age 19, 20% reported
having had more than one partner, and 1%, four or more partners.
* Among women aged 15-24 years who had been sexually active for the
same length of time ( less than 24 months), 45% of 15- to 17-year-olds
reported having had two or more partners, compared with 40% of 18- to
19-year-olds and 26% of those greater than or equal to 20 years of

The following compilation of statistics has some numbers for
premarital sexual partners which may allow you to devise a
semi-realistic average number. You could, I suppose, make the
assumption that for many women, the number of partners posted would
involve those partners before marriage, including her husband.
(whether "affairs" are included in these numbers is anyone's guess, or
partners after death or divorce)
From "STATISTICAL PORTRAIT OF A GENERATION From "HER WAY."
* "According to the Details "Sex on Campus" survey (1996), the average
number of lifetime partners for college men and women is close: 7.2
for men, and 5.7 for women. (Elliott, 17).
* "Recent Glamour reader surveys report even higher numbers of
partners, with the respondents to a 1998 feature reporting a median
number of ten partners (Mansbach, 242); in a 1999 survey, 20 percent
reported at least 20 sex partners. This last survey stands out with
its ambition; it goes beyond lifetime partners to report that a
quarter of respondents have slept with more than one person in the
same night (Boone, 212).
* "In fact, white middle-class college-educated women in their
twenties are widely recognized by researchers to have more sex
partners than any other group of women; the 1995 National Survey of
Family Growth reports that women in these three categories (of race,
income and education) have the highest proportions of four or more
partners over their lifetimes (39).
Again, the number that follows may not be entirely "pre-marital" partners:
From "Primetime Live Poll: American Sex Survey: A Peek Beneath the
Sheets Analysis," By GARY LANGER, with CHERYL ARNEDT and DALIA
SUSSMAN. October 21, 2004.
"Overall, women report an average of six sex partners in their
lifetimes; men, 20. But a better gauge of sexual activity for most
people is the median, the midpoint between the high and low: Women
report a median of three sex partners; men, a median of eight."

Subsequent marital Dissolution Among Women," by Jay Teachman. Journal

"Recent data from the 1995 National Survey of Family Growth indicate
that premarital sex and marriage are linked for a nontrivial
proportion of women (Abma et al., 1997 ). Among ever-married women who
have had premarital sex, nearly 15% experienced first intercourse
within 12 months of marriage and more than 25% had first sex with
their husband. In addition, about 25% of all women who have had sex
have had only one partner in their lifetime, most often their
The Teen Aid Inc, website has a chart correlating the age of first
sexual experience with the number of life partners. It "might" be

Additional statistics that might be of interest, though they do not
provide an answer to your very specific question:
See "Alternatives to Marriage Project."
From the Family and Society Database:
Finding: "Women who begin sexual activity at early ages have far
higher turnover rates among sexual partners (i.e. number of voluntary
sexual partners per year of sexual activity.) Girls who begin sexual
activity at age 13 or 14 have, on average, 1.2 partners per year of
sex activity. By contrast, women who begin sex activity at ages 21-22
have 0.3 sex partners per year of sexual activity. Thus, women who
become sexually active at ages 13-14 have a partner turnover rate four
times higher than those who initiate sex activity in their early

While there are many studies concerning premarital sex, there are
very few containing concrete numbers of sex partners for women before
I truly hope that the few studies I did find prove to be an
acceptable answer to your question. Apparently, they are the only
numbers that appear to be readily available at the present time!
