Can You Get Pregnant Without Sex?
Getting pregnant from anal sex is also unlikely, although the possibility does exist. During anal sex, ejaculation occurs in the anus, which is not connected in any way to the female reproductive tract (i.e., vagina, cervix, uterus, fallopian tubes). But any time semen comes in contact with the vagina (such as if it drips from the anus during anal sex), there is a possibility of becoming pregnant.

Following mutual masturbation, there may be semen (on hands or fingers) that comes into contact with the vaginal area. Therefore, while also unlikely, there is a possibility of pregnancy following mutual masturbation.
