<human>: Can you condense the text into a few key points?

My girlfriend and I have been dating for over 2 1/2 years now and we have both been faithful the entire time.  She received a pap smear this week and tested positive for low-risk HPV with no symptoms.  

She seems to recall that she had a pap smear about 2 years ago when we had been dating for 5-6 months and all tests were negative.  This leads me to believe that it was most likely me who gave it to her.

However, I've been reading on websites that it can lay dormant for years without symptoms and I grow concerned that one of her ex-boyfriends might have given it to her before we started dating.  On the flip side, some websites say that 90% of HPV viruses are dealt with by the immune system in under two years.  Is there a way to know for sure?

Additionally, I heard that smoking can cause HPV in both males and females.  I do smoke.
