How do rhinos mate?

When the females are in season the bulls will fight for the females. After the winner has been chosen the bull will chose the female and then will mate with her.
The bull will place 1/3 of his body on the female. A penis will come out from the males under side. The male will shove his penis up in to the female by pulling in and out of her make more and more sperms go into the female. And thats how they mate.
