A pregnancy only occurs when sperm meets egg, so a woman cannot become pregnant from kissing, oral sex, mutual masturbation, or sharing a hot tub. It is possible for a woman to become pregnant if the man pulls out of her vagina before he comes, but it is less likely than if he comes inside of her. Also, sperm die quickly when exposed to the air, so they do not live long after being ejaculated unless they are inside a vagina. It is very unlikely for woman to become pregnant from a man ejaculating on her clothing or near her underwater. Most accidental pregnancies happen when someone neglects or forgets to use birth control or uses it incorrectly, or when the man intends to pull out but doesn’t make it in time.
