Tired of hearing people say they were "too big" to wear condoms, Emily, an 18-year-old from Utah, took these photos of a condom stretched on her arm to prove otherwise.
Emily, who teaches contraception methods in schools, told BuzzFeed her tweet was originally intended to be a joke, but said it has since provoked many questions about condom size myths.
A common myth is that condoms can be too small and cut off circulation – but as the NHS points out, that isn't the case.
In an online Q&A about condom myths, the NHS says condoms do not break easily, that they can stretch to 18 inches round, and that they are available in many different shapes and sizes.
