Fun fact: their balls and dick are backwards from us. The balls are in front of the peen. As others have mentioned, they can also suck them back into the body so this isn’t an issue. Some other animals can also hide their testes this way like mice and rabbits.

Ah now the pic made sense, I was confused if that was a vulva instead of testes. So is their penises quite long to reach out to the vaginas?

They actually back up into each other. You can tell Kangaroos are about to do it by the audible beep-beep-beep as they approach.

If you’re interested, I highly recommend going down a rabbit hole on kangaroo reproductive anatomy or really just marsupial reproductive anatomy. It’s very different from what you expect with placental mammals like us and most of the mammals we know about or see on a daily basis. The penis curves forward to reach the female. Females have a vulva like other female mammals but they’ve got weirder shit going on internally. Namely the three vaginas and two uteri.
