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 1 , 2 and 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 risk for acquisition and transmission of STIs. The need for sexual behavior data is especially pronounced for individual-based models, 8 , 9 which are becoming more common owing, in part, to the increased availability and affordability of faster, more powerful computers.
