Genital warts are small fleshy growths, bumps or skin changes that appear on or around your genital or anal area. They're caused by the human papilloma virus (HPV) and are the second most common STI in England after chlamydia.
You don't need to have penetrative sex to pass the infection on because HPV is spread by skin-to-skin contact.
The warts are usually painless, but you may notice some itching or redness. Occasionally, they can cause bleeding.
Several treatments are available for genital warts, including creams and freezing the warts (cryotherapy).
