I recently learned that, among others, men who have sex with men (MSM) are at risk for HPV. In fact, the CDC cites infection rates among MSM at about 50% for HIV- ones and nearly 100% for HIV+ men. At the same time, I learned that MSM (and maybe more men) should be getting Anal PAP Smears, which is the first line of detection. If that proves positive, a doctor can take a small biopsy of anal/rectal tissue to test further. Moreover, my understanding is that, when caught and dealt with early, HPV can be removed and monitored and controlled. I saw someone else post and laud the name of the doctor I used, which I completely agree with. Dr. Stephen Goldstone in NYC is EXCELLENT! If you don't live near him, you could try calling his office for referrals to others near you.
