Genital warts are normally bumps or growths caused by various strains of HPV which is one of the more common STDs.
For males you would find the warts on the penis, scrotum, groin or thigh. They can be bumps or flat,small or big. Many times they are flesh coloured. It could be months or years for the symptoms of the infection to appear.
Genital warts are passed through sexual contact. If you have genital warts and engage in sexual contact you pose the risk of passing it to your partner.
There is no actual treatment for genital warts doctors do treat the health problems that are associated with them. There is a vaccine that is currently being used to treat females but hasn’t been approved for use in males.
