Genital warts are caused by a virus known as HPV. It is impossible to be infected with HPV through the sharing of clothes, towels, or objects of personal hygiene. The most common way for HPV to spread is through skin-to-skin contact, usually during sexual activity. The general symptoms of genital warts are the presence of small, flesh-colored bumps in the genital area. In case you happen to be concerned about HPV then the best thing to do is to talk to a healthcare provider about preventing and treating it.
