Hi,
Types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68 are "high-risk" sexually transmitted HPVs and may lead to the development of cervical intraepithelial neoplasia (CIN), vulvar intraepithelial neoplasia (VIN), penile intraepithelial neoplasia (PIN), and/or anal intraepithelial neoplasia (AIN).
Penile intraepithelial neoplasia is associated with chronic infection with human papilloma virus (HPV), the cause of genital warts.
Lesions are single or multiple small red plaques on the glans or inner aspect of the foreskin. They may have a smooth, velvety, scaly or warty surface. The following signs and symptoms may occur: Redness and inflammation,Itching,Crusting or scaling, Pain,Ulcers and Bleeding.

Since you do not have any of the above and you have already seen a doctor, I don't think you should worry.Also HPV types 6 and 11, which cause 90 percent of genital warts will manifest as outgrowths which are obvious.
Anyway since there is currently no cure or treatment for HPV infection there is nothing you can do at this stage.A skin biopsy can be performed to confirm the diagnosis if you are so anxious but that will require you to visit a dermatologist.

I also observed similar patch about 2mm last week. Now it appears to have increased to about 3mm. No pain, irritation or any other symptom other than the what you see when closely inspected. I am 56 and always had safe sex.
Further I experienced a very mild pain, on and off (few months) in lower abdomen above my right testicle. can they have connection, Is this white patch to be taken serious? please advice.
