So my girlfriend and I have been in a relationship for some time now, and we have progressed toward knowing each other more physically. We have never had sex, and it is implicit that we should avoid it for the sake of safety.
Recently, we were together, and she gave me a hand job. After a few minutes, I went a cleaned up, using soap and water, and shampoo, and when I came back we spent some more time together, and I proceeded to finger her.
Now here is the question: Is there any legitimate chance that the contact I had with my own semen, some of which landed on my body, might result in her getting pregnant? I am fairly convinced that this is impossible, however, I can't help but entertain some irrational fears.
