Yesterday I went to my girlfriend's house, we kissed for a few hours and that's it. I wanted to pull my pants a little higher and I reached with my hand on my underwear which were soaked in some pre-ejaculatory liquid. I felt that she was wet, I took her hand (I don't remember if I wiped myself) but until then I kissed her, we touched our bodies and hands. After about 10-20 minutes, I inserted my finger into her vagina. I am very scared that she will be pregnant. My life will be ruined if this happens
