Can pregnancy result from messing around without intercourse?

No: While theoretically possible to get pregnant from sperm on the outside of the vagina, typically sperm has to be inserted into the vagina in order for a woman to get pregnant. Given 'messing around' is a broad description, it's hard to give you an accurate answer, but if there was no penetration, the answer is likely no, no pregnancy.

No: There must be vaginal penetration and ejaculation into the vagina!
