Imiquimod
"I never leave reviews but I wanted to for anyone else in my spot and wants sound advice.  I had about 10-12 small warts above my penis (pubic hair area) and 3 on the shaft.  

For the "larger" warts on the shaft, I received liquid nitrogen treatment which did not work well - one returned after a month and it had no impact on the other two.

I was also prescribed aldara to be used 5x weekly (M-F).  Let me be clear - FOR THE FIRST 6 WEEKS IT DID ABSOLUTELY NOTHING.  I was let down but continued to apply it diligently.

Finally, on week 7 things started getting red and inflamed.  This lasted for 2-3 weeks at which point things began healing and now look FLAWLESS.  Highly recommended, but BE PATIENT"
