It sounds like you need to do a little more research about HPV ladydeadlock. There are several strains of HPV out there and Eiri's right, certain strains do cause cervical cancer.
Another thing is that unless you have had a colposcomy, your doctor could not have determined that you have HPV. Your doctor could determine that you have displacia and have some cells that could become cancerous from your normal pap, but the actual diagnosis comes from a more indepth analsis of the bad cells. I know this because I was diagnosed with it several months ago and have recently gone through treatment and now I have received a clean pap.
HPV can be treated, but becuase it is a virus, it can never be cured. It can become dormant in your body and can be reactivated for no particular reason.
You can get HPV from sex, but as Eiri said there are several other ways of contracting it. You can get it from kissing or oral sex. It is an STD, but did you know that 70% of all females in this country have HPV. It is a very common virus that is treatable, but not curable.
I think that you need to do some more research before you give up on your doctors. And yes they do want your money, but they also want to help you. Try typing HPV in google, and also look on webmd for some answers. It will put your mind at ease.
PM me if you have any specific questions - like I said, I have recently gone through this.
