Coitus interruptus - colloquially referred to as withdrawal - is an attempt at contraception wherein the penis is removed from the vagina prior to ejaculation, with ejaculation occurring somewhere outside the vagina. Although withdrawal can reduce the risk of pregnancy, it is less efficacious than methods such as consistent condom use and hormonal birth control. Consequently, it is of public health importance to identify sociocultural influences that either increase or decrease the likelihood of withdrawal as a contraceptive technique. Multiple content analyses have identified external ejaculation as common in popular pornography, yet no study appears to have assessed whether more frequent pornography consumption increases the likelihood of withdrawal behavior. Using national probability data, the present study examined whether pornography use and withdrawal were correlated among U.S. women aged 15-49. Women who consumed pornography more frequently were more likely to report using withdrawal as a contraceptive method than women who consumed pornography less frequently, but this association was moderated by perceptions of pornography's utility and women's marital status. Results are discussed through the lens of the sexual script acquisition, activation, application model (AM) of sexual media socialization.
体外射精——通俗地称为抽出法——是一种避孕尝试，即在射精前将阴茎从阴道抽出，使射精发生在阴道外的某个地方。虽然抽出法可以降低怀孕风险，但它不如持续使用避孕套和激素避孕等方法有效。因此，识别那些增加或降低抽出法作为一种避孕技术使用可能性的社会文化影响因素具有公共卫生意义。多项内容分析表明，体外射精在流行色情作品中很常见，但似乎没有研究评估过更频繁地消费色情作品是否会增加采用抽出法的可能性。本研究利用全国概率数据，调查了15至49岁美国女性中色情作品使用与抽出法之间是否存在关联。与较少消费色情作品的女性相比，更频繁消费色情作品的女性更有可能报告采用抽出法作为避孕方式，但这种关联受到对色情作品效用的认知和女性婚姻状况的调节。研究结果通过性媒体社会化的性脚本获取、激活、应用模型（SAM）进行讨论。
