Unwanted Sex And Unwanted Conception

I was 17 working after school and this man took advantage, to be polite, of me and I had a son. He is going to be eighteen. I have never divulged to him or anyone else exactly what happened that evening. It happened, and I got pregnant. The story I have stuck with all these years is that he was a friend who moved and I gave him sex as a goodbye present but I never wanted him in my life.

Now my son is going to look for his father online. Using DNA for a match. I don't want him to know his father, who his father is, and much less how he came about. It's my secret to keep.
