If i have genital warts and i go ice swimming, will my genital warts fall off due to the freezing temperature of the water?

Probably not.: I'm not sure that I would recommend this course of action even if it did work, as icy cold water exposure is asking for a lot of trouble (frostbite, anyone?). That being said, genital warts will not freeze off at 32 deg F, or even 30 deg F (below freezing). Freeze spray using liquid coolant used by dermatologists cools the surface to below 0 deg F; water will never be that cold (but ice will be).
