It is impossible to get pregnant if the penis does not enter the vagina at all, if it is stimulated to ejaculate outside the body, and if it does not enter the vagina after ejaculation. Only if the sperm is ejaculated in the vagina, or if a small amount of semen is left in the vagina, the sperm will enter the uterine cavity along the cervix and reach the fallopian tubes to unite with the egg. If the sperm is stimulated outside the body and then ejaculated outside the body, it is not possible to get pregnant. The sperm that is ejaculated outside the body will soon die in the external conditions, so it will not achieve pregnancy.
