Hello,
In 90% of cases, the body’s immune system clears HPV naturally within two years.  But, sometimes, HPV infections are not cleared and can have HPV even if years have passed since he or she had sexual contact with an infected person.  There is currently no FDA-approved test to detect HPV in men. Genital warts can be diagnosed through visual examination of the penis and surrounding areas.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
