If you have HPV, it is still recommended to use protection during sexual activity. While having HPV does not offer immunity against getting reinfected with different strains of the virus, using protection can reduce the risk of transmitting or contracting other sexually transmitted infections (STIs). It's beneficial for both your health and that of your partners to practice safe sex regardless of already having HPV. If you have conflicting advice from doctors, consider seeking a third opinion or consulting a specialist in this area for further clarification on how best to protect yourself and others.
