Hello, I come here with an embarrassing problem, in the beginning I will say that I have knowledge about sex education, and I just want to make sure or dispel my doubts, because I am a hysteric, I am 18 years old. I did petting with my girlfriend and everything would be fine because we did it in clothing (she had 3 layers and I had 2) and I have no doubts about it, but later I took off her clothes and rubbed her through underwear in the vaginal area. That was just two moves up and down. I did not push, literally, that was a light brush, but I had pre-ejaculate on my penis and there are my doubts about pregnancy, because she had fertile days. I didn't ejaculate and I think my semen could be of poor quality because I masturbated twice in the same day. My girlfriend has had vaginomycosis for a longer period of time, which can also have some effect. I apologize for the long question but I would just like to know the opinions of the specialist about my problem.
