According to data from the 1991 National Survey of Adolescent Males, condom use is likely to be highest at the beginning of relationships and to decline as the relationship continues. The proportion of sexually active men aged 17-22 who used a condom with their most recent partner declined from 53% the first time they had intercourse with that partner to 44% at the most recent episode. Condom use also decreases with age; 59% of 17-18-year-olds used a condom the first time they had intercourse with their most recent partner, compared with 56% of 19-20-year-olds and 46% of 21-22-year-olds. However, the probability that the female partner used the pill the first time that the couple had sex increased with the man's age--from 21% among 17-18-year-olds to 35% among 21-22-year-olds. Young men were more likely to have used a condom if they thought their partner was sexually inexperienced, and less likely to have done so if they suspected their partner was at high risk for an STD.
根据1991年全国青少年男性调查的数据，避孕套的使用在恋爱关系开始时可能最高，并随着关系的持续而下降。17至22岁有性行为的男性中，与最近一位伴侣使用避孕套的比例从与该伴侣首次性交时的53%下降到最近一次性交时的44%。避孕套的使用也随着年龄的增长而减少；17至18岁的男性在与最近一位伴侣首次性交时，59%的人使用了避孕套，相比之下，19至20岁的人这一比例为56%，21至22岁的人则为46%。然而，在这对情侣首次发生性行为时，女性伴侣首次使用避孕药的可能性随着男性年龄的增长而增加——从17至18岁男性的伴侣中的21%增至21至22岁男性的伴侣中的35%。如果年轻男性认为其伴侣没有性经验，他们更有可能使用避孕套；而如果他们怀疑伴侣感染性传播疾病的风险很高，则使用避孕套的可能性较小。
