Help for Genital Warts

Ive had the acid treatment to them, and I was even given a prescription gel to remove the warts, they were gone for about a month or so, now they’ve come back and I seem to be growing new ones, is there some other kinda treatment, antibiotics i can look into, to remove them permanently? I read everywhere that your normal immune system can fight them off usually, and I don’t have any kinda of immune disorder or disease, I don’t have HIV, so what’s the problem??

I have been with my girlfriend since August of 2008 and back in March 2009 she had a abnormal paps then again in September 2009 another abnormal paps. Well about two months ago I noticed some pumps showing up on my penis. I finally got in to see a doctor yesterday and he confirmed that it was HPV and that I have genital warts. We have no idea who was the original carrier of this and who gave it to who but it is here now. She is showing no physical signs like I am besides the abnormal paps. The doctor told me she might not show signs because her body is different then mine and her body is fighting off the virus were mine didn’t even though we both have it. She called here doctor and he confirmed that her abnormal paps were from HPV and unless she is showing signs (warts) not to worry. My doctor has given me three choices surgery to remove them try a cream or just leave it alone and see if it goes away. My choice was the cream but when I went to the pharmacy the cream was $700 and my insurance only covered $200 so it was going to cost me $500 for the cream. I did not get the cream until I check into any other options of treatment. My question is has anyone had this happen to them before and what did they do to get rid of the genital warts?
