Q: If me and my boyfriend only had oral sex, and he came before me and his fingers are covered in his cum, and after that he fingers me, could it cause pregnancy?
A: Yes, it is possible. In order for fertilization to occur, a viable sperm and egg must come in contact with one another, after the sperm has traveled on its own through the vaginal tract and the cervix. Sperm does not live very long outside the body, but if he had relatively “fresh” semen on his fingers and then he essentially pushed that semen into your vagina, pregnancy would indeed be possible.
If you are concerned that you might be pregnant, consider taking a pregnancy test to put your mind at ease. If this just happened in the last few days, you might even consider taking emergency contraception if you are not using any other kind of birth control, such as the pill, patch, shot, ring, or IUD.
Protection Is At Hand
Additionally, your partner might want to look into using a finger cot, which is a small condom designed for preventing fluid transmission during fingering. Washing your hands prior to insertion into any body region is a good practice to prevent transmission of bacteria to prevent getting an infection. Using a male or female condom can be very effective in preventing an unintended pregnancy as well as preventing a sexually transmitted infection but must be worn from start to finish of each and every sex act to be most effective.
