Can you get pregnant having anal sex? Is true that when air hits sperm, it dies?

Hello. . Hello. You can't get pregnant from oral sex alone. The sperm does not die immediately upon hitting air. However it will die much more quickly than if kept in a warm, moist environment, like a woman's body.
Not likely. I could think of some strange circumstances, but they would literally be first time case reports. On the other hand, leakage of semen from the anus onto the labial surface and then into the vaginal opening is not inconceivable, but have never heard of this actually occurring.
