BBC News By Rachel Stonehouse image copyrightGetty Images Two years ago Gemma (her name has been changed) had sex with a man who removed the condom without her knowledge or consent. Stealthing - or non-consensual condom removal - is rape under UK law, but there's only ever been one successful prosecution, and that was in 2019. "I didn't know anything about stealthing until it happened to me," she tells Radio 1-Newsbeat. "It was only afterwards I realised what he'd done and I felt so upset and worried. "I got the morning-after pill, but when I didn't get my period the following month I took a pregnancy test."
