Can you get pregnant by putting a finger in your butt?

No you cant. To get pregnant 1 you have to be female 2 you have to be old enough to ovulate. 3 Sperm which is ejaculated from the penis of a male has to enter the vagina. That is the opening in front of the anus just under where the urine comes from. there is nothing in the "but hole" anus that can develop a baby nor is there anything a finger can do to start a pregnancy no mater where you put it.
