Can I get Pregnant with Oral Sex?

Only one type of sexual activity will not result in pregnancy, oral sex. Stimulating your partner's genitals with your lips and tongue does not allow sperm near your precious egg, so you can be confident that no unexpected pregnancy will result. 

Even if semen one swallowed, there is no communication between your gastrointestinal tract and your reproductive system so no sperm can enter the vagina through this route.
