25% chance or lower which is the same as any couple who has unprotected sex. It's not likely, but yes it's possible.
Yes, there is still a chance she can get pregnant...
So there is a big chance she can get pregnant?
As said, it doesn't matter. Penetration is still penetration and saliva does not kill sperm. If you don't want to get her pregnant don't ever have ANY form of unprotected sex no matter if it's for 1 hour or for 1 second.
there is still a chance. if she was ovulating she could be pregnant.
Um what if she used her mouth to wipe it off?
Yes, ANY time you have unprotected sex, no matter what length of time, there is a possibility for pregnancy... If you do not want a child, then you need to use protection.
