Back in high school, I dated a wonderful girl for a year and we were totally hot and heavy for each other, but she suddenly moved out of state and I never saw her again.

About a month ago, she called me out of the blue and told me that I am the father of her 10-year-old daughter and she has cancer and she needs me to help her with some bills.

At first, I didn't believe her, but she sent me a picture and the girl is almost the spinning image of me. I want to believe that I am the father and I would like step up to the plate and all, but I don't know how I could have knocked her up when the only time I fully ejaculated was one time when she went down on me for a longer period of time than usual.

However, I recall one time we were dry-humping and her underwear pulled to one side and a little of my pre-ejaculate might have come into contact with the outside of her private area. Is there any possible way that she could have gotten pregnant, or is it time for a paternity test?
