Leading medical and public health societies endorse comprehensive sex education, but only 20 states and Washington, D.C., currently require information about contraception when sex education is taught, and even fewer require the inclusion of topics such as gender diversity or consent. At the same time, social media use, especially the video-sharing app TikTok, is increasing among teens. TikTok, therefore, offers a novel opportunity to make up for shortcomings in sex education and convey sexual health information to adolescents. To describe the availability and content of sexual education on TikTok, we conducted a content analysis of themes for 100 sex education-focused videos. We found that female anatomy was the most frequently addressed topic. Sexual pleasure was the second most common theme, within which discussions of the female orgasm and arousal constituted the most common subtheme. Other common themes include contraception and sexual health. These sought-after topics may be incongruent with those presented in standard school- or home-based sex education or interactions with health care providers, and this disconnect suggests opportunities for health care providers and educators to initiate conversations or offer resources on these themes as part of routine interaction. We conclude with recommendations for future research to consider the factual accuracy of sex education on TikTok and determine how exposure to this content affects adolescents' understanding of the risks and benefits of intercourse, sexual practices, age- and gender-based sexual norms, and other health behaviors.
