GW can appear anywhere from a few weeks to a few years, however most likely a few months after exposure. It's rare for them to appear years after but it's been known
i was more thinking it could be because i was itching a lot could i have cut myself and it jsut be healing now? if it was like genital warts how long after sexual contact would they start to appear?
Probably not to do with a yeast infection from the sounds of the description. Could be something completely harmless, but if your sexually active then go get them looked at
