We don't have referrals to healthcare providers who specialize in HPV per se, but urologists or dermatologists are often good choices for men. General practice providers are usually fine, as well. Sometimes a Web site for a local hospital, especially if it's affilated with a college, will have "find a provider" tools.
I know this must be difficult for you, as we know the psychological impact of having warts is both very real and often overlooked. Warts are almost always a condition that can be managed and seldom causes long-term issues, but that's little comfort to you right now! Keep posting and let us know how you are.
Hope this helps.
