I have fingered my girlfriend quite a few times now. I can only get one finger up there and she never seems to react, just stands there as if nothing is going on. Am I doing something wrong?

My best friend recently confided in me that immediately after her boyfriend ejaculated on her leg, she swiped some of the semen with her fingers and proceded to enter them into herself in hopes to get pregnant. We were talking about this and I asked if you actually could get pregnant this way and neither one of us knew the answer. Now that's my question for you. Is it possible to get pregnant this way?
