1. Genital Warts. This is the most common of all symptoms associated with HPV and usually, what alerts people to the fact that they have an infection. Genital warts can appear as flat lesions, stem-like outgrowths or even cauliflower-like bumps. In women, they are mostly found on the vulva, though in some cases the cervix, vagina or anus may be affected. In men, the penis, scrotum and anus are sites of occurrence. These warts are not painful in most instances though sometimes they may itch.
