If i was rubbing genitals with my girlfriend, with both of us having jeans and underwear on, and i came, could she be pregnant? i did not stop after ejaculation to clean up, and we continued intermittently for the next half hour.

See below: For conception and pregnancy to occur, it generally requires some degree of penile penetration and ejaculation within or into the vagina. That said, sperm can potentially remain viable for up to an hour outside the body, so ejaculation just outside or in region of the vagina “could” result in conception in a very small percentage of such occurrences.
