I am 17 years old and I have recently met a girl who is 16, we went out one night and 1 thing led to another and I was ready to have sex, but she said she can't, I thought she was just scared cos she was a virgin but the next day the explained to me the situation, the female side of her family (mother, grandmother and so on) have cervical cancer in their history, meaning she has the cells which can become cancerous and she has told me that cells from my penis during intercourse can trigger the cells to become cancerous therefore giving her cancer, I didn't fully understand everything she was saying to me because I have never heard about it before and I saw how much talking about it affects her emotionally so I am trying to completely avoid talking to her about it, that's why I came here so I can ask about it....

Will intercourse really trigger it?
If it does then if I wear a condom will that make any difference?

I really like her and in time might even fall for her but it probably sounds like i'm just thinking with my d!ck, I just want to understand what CAN go wrong and the limitations we have e.g. completely no penetration (anal), oral sex etc etc

If I sound like a fool I completely accept it....

Thanks for reading and I hope to receive an answer soon as I am going to see her tomorrow.
