I think you may get a yeast infection from a partner with candidal vaginitis. It usually appears as small white spots, redness, or a dry, peeling rash on the penis accompanied by itching, irritation, or burning.
Your girlfriend may also experience the same symptoms in her “down there”. Both you and her should get treated at the same time and abstain from sex until the infections heal. A topical antifungal cream like Fugacil can give you symptom relief.
