HPV infections are usually spread by skin to skin contact with infected people. In your case, sex with multiple partners may have caused the spread, as someone you had sex with may have genital warts. Warts are symptoms of HPV infection caused by Human Papilloma Virus. They are of different sizes and shapes and are usually shaped like a little cauliflower. It can occur months after getting infected from an infected partner. It can also stay dormant in body without showing any symptom of infection. You can leave those warts as such and it may go away after some time. Chances are there for a recurrence, spread or increase in number of warts. This depends on the immunity power of your body. It is better to leave them unattended till you can see you doctor, if the warts stay same and not increasing in number. You can try podophyllum or Warticon to remove warts and to reduce their spread. Many other removal options like cryotheraoy, laser treatment, surgical excision etc. are available. Hope it helps. Take care always.
