Although three-fifths of adolescent males aged 15-19 say they have had sexual intercourse, analyses of data from the 1988 National Survey of Adolescent Males indicate that their level of sexual activity is relatively moderate. The data show that among sexually experienced young men the mean number of partners in the last 12 months is 1.9, and the mean frequency of intercourse in the last four weeks is 2.7 times. Black males have had more partners than white or Hispanic males; however, after the number of years since first intercourse are controlled for, these differences disappear. On average, sexually experienced youth spent six out of the last 12 months with no sexual partner, and only 21 percent of sexually active males had more than one partner in any month in the last year. Comparisons with 1979 data suggest that proportionately more adolescents were sexually experienced in 1988, but fewer non-black males had first intercourse before their 15th birthday. The number of partners since first intercourse and in the past four weeks appears to have decreased, as has the frequency of intercourse in the last four weeks.
尽管15至19岁的青少年男性中有五分之三表示他们有过性行为，但对1988年全国青少年男性调查数据的分析表明，他们的性活动水平相对适中。数据显示，在有性经历的年轻男性中，过去12个月的平均性伴侣数量为1.9个，过去四周的平均性交频率为2.7次。黑人男性的性伴侣比白人或西班牙裔男性更多；然而，在控制首次性交后的年数后，这些差异就消失了。平均而言，有性经历的年轻人在过去12个月中有6个月没有性伴侣，并且在过去一年中，只有21%的性活跃男性在任何一个月中有不止一个性伴侣。与1979年的数据相比，表明1988年有性经历的青少年比例相对更高，但非黑人男性在15岁生日前首次性交的人数减少了。自首次性交以来以及过去四周内的性伴侣数量似乎有所减少，过去四周内的性交频率也是如此。
