Hi there ideefixe2,
Thanks for the post. The most common treatments for external genital warts are TCA and cryotherapy. TCA is a non-toxic liquid caustic acid. TCA is well tolerated by patients, but significant burning or pain may occur to the applied area for 2 to 5 minutes. TCA is usually applied in the clinician's office weekly (or every other week) until warts are gone. This treatment may cause mild scarring. TCA can be used in the vagina, perianally, on the penis, and urethra.
Cryotherapy is when the clinician applies liquid nitrogen to the external genital warts. The outer layer of tissue forms a blister and eventually breaks off from the deeper layers, taking most of the affected skin with it. It may sting when the liquid nitrogen is applied to the wart, but generally no pain is felt afterwards. One treatment may be sufficient, but others may need to have the procedure repeated. Very minimal scarring (if any) where the treatment was applied to the wart. Cryotherapy can be performed vaginally, perianally, on the penis, cervix, or the urethra.

Hope this helps, and post again if you think of anything else.
All the best,
