Using data from the — National Survey of Family Growth, we found that lifetime number of vaginal sex partners is positively associated with the number of sex partners in the past 12 months and negatively associated with age at first vaginal intercourse among to year-old male and female respondents.
Studies have shown an association between lifetime sexual behaviors and age at sexual debut 12 sex women in United States recent sexual behaviors 3 ; however, few studies have examined the relationship between these behaviors using data from national surveys.
National data focusing on sexual behaviors are important to sexually transmitted infection STI research and prevention.
Such data can be useful in many areas, including informing mathematical models of STIs, understanding epidemiological trends in STI incidence, and targeting prevention resources to those at highest sex women in United States for acquisition and transmission of STIs. The need for sexual behavior data is especially pronounced for individual-based ladies looking hot sex WI Iron river 54847, 89 which are becoming more common owing, in part, to the increased availability and affordability of faster, more powerful computers.
The sex storys sister of this study was to examine the distribution of sexual behaviors in the United States stratified by the lifetime number of vaginal sex partners.
Our main contribution to the existing literature is use of recent, nationally representative data. Such data are useful 1 to illustrate heterogeneity in sexual behavior by sex, age, and lifetime number of sex partners to aid STI prevention efforts and 2 to inform mathematical models of STIs that often classify the population according to sexual activity level, based on the frequency at which people acquire new sex partners. We created 5 sexual activity sex women in United States according to self-reported lifetime number of sex partners, where sex was defined as heterosexual vaginal intercourse and same-sex partners were excluded: These groups are similar to those used in a recent individual-level model of human papillomavirus HPV vaccination and were modified based on previous research to be useful to other STI prevention and modeling efforts.
We analyzed 3 sexual behavior measures. First, we examined the distribution of the population across the sexual activity groups, stratified by sex and age using 5-year groupings. Second, for each sexual sex women in United States group, we calculated the mean number of recent vaginal sex partners past 12 monthsstratified by sex and age group.
Third, for each sexual activity group, we examined age at first vaginal intercourse among those aged 25—34 years stratified by sex.

Recent data are most useful for sexually transmitted disease prevention efforts including modeling. For the distribution of number of lifetime vaginal sex partners, we found similarities across age groups for male and female respondents, with a few minor exceptions.
Among to year-olds, sexual activity group 1 0—1 lifetime sex partners was the most frequently reported sexual activity group for male However, among women aged 25 to 44 years, sexual activity group 2 2—4 lifetime sex partners was the most frequently reported sexual activity group sex women in United States Confidence intervals can be found in Appendix A.
The actual value for to year-old boys who reported 0 to 1 lifetime sex partners is The mean number of recent sex partners past 12 months varied according to lifetime number of sex partners; however, within sexual activity groups, we found few sex women in United States differences by age or sex Fig. Although male respondents reported significantly more recent partners than female respondents overall with the exception of those 15—19 years oldwithin a given sexual activity group, the reported numbers of recent vaginal sex partners did not significantly differ for male and female ladies want casual sex ME West buxton 4093 by age group.
For clarity of illustration, the vertical axis was truncated at 3. Age at first dex intercourse varied according to lifetime number of partners Fig. In general, those with higher numbers of lifetime sex partners reported a younger age at first vaginal intercourse than those with lower numbers of lifetime sex partners.

Male and female respondents reported similar ages sex women in United States first vaginal intercourse for all sexual activity groups, except for sexual activity group 1 0—1 lifetime sex partners.
Within sexual activity group 1, more male respondents For sexual activity group 1 0—1 lifetime sex partnersthe actual value of first vaginal sex at age 18 to 24 years is Our findings that lifetime does your guy friend like you quiz of sex partners is associated with a the number of sex women in United States sex partners and b age at sexual debut are supported by other studies.
A key theme of our results is that lifetime number of sex partners is a simple yet useful measure womwn capture heterogeneity in sexual activity. When controlling for lifetime number of sex partners sexual activity groups 1—5 in our applicationwe found no significant differences between men and women in sex women in United States reported number of recent Unitted partners and b age at sexual debut except as noted above for sexual activity group 1.
The sexual activity groups we used were similar to, but not exactly the same as, the sexual activity groups used by Van de Velde and colleagues. Our analysis is subject to limitations. Responses to the interviewer-administered survey could be subject to social desirability bias.
The measure for the number of sex partners in the past 12 months was top coded at 7, which could sex women in United States the mean but also prevents extreme outliers from skewing the results. Sexual behaviors only included heterosexual vaginal sex partners in our analyses because we wanted to focus on vaginal sex in the lifetime; therefore, other sexual risk behaviors such as oral and anal sex were not accounted for in these analyses. Sample sizes precluded analyses by other sociodemographics.
To facilitate the use of our results in future STI prevention efforts including models, the sexual activity groups we used were selected based on a recent model of HPV vaccination. Statse sex women in United States limitations, our analysis provides useful data on sexual behavior by age, sex, and lifetime number of vaginal sex partners.

Furthermore, our analysis illustrates the potential usefulness of lifetime number of sex partners as a simple classification to reflect heterogeneity in other sexual behaviors.
The examination of sexual behaviors by age groups and by sex is important for sex-specific, age-related Statew and prevention programs such as screening for chlamydial infection sex women in United States22 and HPV vaccination 23 The findings and conclusions in this report are those of the authors and do not necessarily Statfs the official position of the Centers for Disease Control and Prevention.
