Is it possible to get pregnant from rubbing sperm into your vagina even though it has already hit air? and i'm ovulating. been off birth control.

YES.: Especially if you are near ovulation, the chance of getting pregnant is higher. Sperm has been shown to live up to a week in the vagina. Even if it is exposed to air, the fluid it is contained it can protect it.

Without the Father: Any attempt to cause a pregnancy without the consent and knowledge of the male can lead to significant legal and ethical problems. I would advise you to get a legal opinion about this very unfortunate plan of yours.
