My boyfriend and I engaged in mutual masturbation a week and a half ago. He ejaculated and wiped himself clean with a Kleenex, with a minimal amount landing on his hands. Both him and myself proceeded to the washroom where we both washed our hands with soap and warm water. He dried his hands numerous times including the bathroom towel. About 5 or 10 minutes after this, with completely dry hands, and in the spur of the moment, he penetrated me with his finger. This was after he had also been rubbing his fingers over my clothing. My period is always irregular. Usually between 5 or 6 weeks, and sometimes even 7. I was already 2 days late when this happened (as in 30 days since last period, which isn't that late for me at all)...it has been a week and a half since and still no period. Could my elevated stress be preventing the period, or is it actually possible that we could be pregnant? Does soap and water have a good chance at effectively killing or at least removing sperm? Was it down the drain or still on his hands? Any serious answers would be appreciated.
