This report presents data on the prevalence of oral sex with opposite-sex partners and the timing of first oral sex relative to first vaginal intercourse among females and males aged 15-24 based on the National Survey of Family Growth (NSFG) data from 2007-2010. The question on timing, added to the NSFG in 2007, asked females and males whether first oral sex occurred before, after, or on the same occasion as their first vaginal intercourse.
Descriptive tables of numbers and percentages are presented and discussed. The current report is based on a nationally representative subsample of 6,346 interviews conducted from July 2007 to June 2010-3,242 with women and 3,104 with men aged 15-24 years. The measures presented in this report were collected using audio computer-assisted self-interviewing, in which the respondent enters his or her own answers into the computer without telling them to an interviewer. The overall response rate for the 2006-2010 NSFG was 77%, 78% for women aged 15-44 years, and 75% for men aged 15-44 years.
About two-thirds of females (66%) and males (65%) aged 15-24 years in 2007-2010 had ever had oral sex. Among females aged 15-24 years. 26% had first oral sex before first vaginal intercourse; 27% had oral sex after intercourse; 7.4% had oral sex on the same occasion as first intercourse; and 5.1% had oral sex, but no vaginal intercourse. Among males aged 15-24 years, 24% had first oral sex before first intercourse; 24% had oral sex after first intercourse; 12% had oral sex on the same occasion as first intercourse; and 6.5% had oral sex, but no vaginal intercourse.
本报告基于2007 - 2010年全国家庭成长调查（NSFG）的数据，呈现了15至24岁的男性和女性与异性伴侣进行口交的流行情况，以及首次口交相对于首次阴道性交的时间。2007年添加到NSFG中的关于时间的问题，询问了男性和女性首次口交是在首次阴道性交之前、之后还是与首次阴道性交同时发生。
展示并讨论了数字和百分比的描述性表格。本报告基于2007年7月至2010年6月进行的6346次访谈的全国代表性子样本——其中3242次访谈对象为15至24岁的女性，3104次访谈对象为15至24岁的男性。本报告中呈现的测量数据是通过音频计算机辅助自我访谈收集的，即受访者在不告知访谈员的情况下将自己的答案输入计算机。2006 - 2010年NSFG的总体回应率为77%，15至44岁女性的回应率为78%，15至44岁男性的回应率为75%。
在2007 - 2010年，15至24岁的女性中约三分之二（66%）和男性中约三分之二（65%）曾有过口交经历。在15至24岁的女性中，26%在首次阴道性交之前首次进行口交；27%在首次阴道性交之后进行口交；7.4%在首次阴道性交的同时进行口交；5.1%有过口交经历但没有阴道性交。在年龄为15至24岁的男性中，24%在首次阴道性交之前首次进行口交；24%在首次阴道性交之后进行口交；12%在首次阴道性交的同时进行口交；6.5%有过口交经历但没有阴道性交。
