I came in a girls mouth and she wiped it off with a wet wipe. she was adamant about keeping the wipe. could she use that wipe to impregnate herself?

A thing called trust: Any way imaginable that gets some fresh semen to the inside of the vagina can start a pregnancy (a new baby, family life, etc...). Human imagination is limitless. Fertile couples having sexual activities base decisions on trust and faith... we hope. A good rule is not to squirt any sperm out anywhere near another person unless there is mutual trust and common goals.
