Hi,
Well, you don't have to worry about genital warts if you've never had sexual contact (vaginal, anal, or oral) with another person. Genital warts are spread by skin to skin contact, from one person to another usually during sex...
It would be a good idea to speak with your doctor again; explain that the growths (cysts?) are spreading and that you are concerned about them. The doctor will probably have you make an appointment for another pelvic examination soon. Meanwhile try not to panic, most cysts aren't serious, and can easily be treated if they become bothersome.
Take Care
