Warts are caused by viruses and can appear anywhere on the body. Those that show up in the genital area are caused by the human papillomavirus, commonly called HPV, and are easily transmitted by sexual contact.
HPV infection is the most common sexually transmitted disease (STD) in North America. Certain forms of the virus can cause cervical, rectal, vulvar, vaginal, and penile cancer. According to the CDC, at least 50% of sexually active men and women will get a genital HPV infection at some point in their lives.
Much of the information about HPV virus (human papillomavirus) centers on women, since having the virus increases their risk of getting cervical cancer. But HPV virus in men can cause health problems, too. It's important for men to understand how to reduce the risks of HPV infection.
HPV infection can increase a man's risk of getting genital cancers, although these cancers are not common. HPV can also cause genital warts in men, just as in women.

After a person has been infected by HPV, it may take one to three months (or longer in some cases) for warts to appear. Some people who have been infected never get warts.
What Do Genital Warts Look Like?
Genital warts look like small flesh-colored, pink or red growths in or around the sex organs. The warts may look similar to the small parts of a cauliflower or they may be very tiny and difficult to see. They often appear in clusters of three or four, and may grow and spread rapidly. They usually are not painful, although they may cause mild pain, bleeding, and itching.
Genital Wart Symptoms
Like many STDs, HPV does not always have visible symptoms. But when symptoms do occur, warts may be seen around the genital area. In women, warts can develop on the outside and inside of the vagina, on the cervix (the opening to the uterus), or around the anus. In men, they may be seen on the tip of the penis, the shaft of the penis, on the scrotum, or around the anus. Genital warts also can develop in the mouth or throat of a person who has had oral sex with an infected person.
Because there is no way to predict whether the warts will grow or disappear, people who have been infected should be examined and treated, if necessary.
