I'm concerned about my girlfriend's possible pregnancy. First, I ejaculated on her breasts. A few minutes later, I wiped all of this ejaculate away with a tissue. A few minutes later, I fingered her quite deeply. I don't believe there was any ejaculate left on my hands at this time, though I couldn't be sure - my penis had trailed some down her stomach, for example. Is there any danger she could be pregnant?
