Do kangaroos have 2 penises

No

It is snakes that possess 2 separate and distinct penes ... and just a couple of lizard species as well. Snakes are almost unique in this thing.

In addition:

No mammals actually have two penises, or penes, but most marsupials have a bifurcated penis, meaning they have two tips on their penis. This may be the basis for this question. Whilst many wallabies have this feature, neither of the two largest species of kangaroos (Red Kangaroo or Grey Kangaroo) have a bifurcated penis.
