That's true also but I thought that part was pretty obvious so I left it out. Thanks for your input.
Although Chima7 is correct that you cannot get pregnant that way... You also need to understand something else...
Sperm need to enter vaginally to get to your egg... That's the way you can get pregnant.
Yes, the acid in your stomach will most likely kill the sperm... BUT, the sperm will never reach the inside of your uterus to get to the egg by going through your mouth.
No you can't get pregnant that way because your saliva and/or the acids in your stomach that help your food to digest will kill the sperm.
