Unlike snakes and lizards, crocodiles do not have a hemipenis. Their penis is fully erected at all times. Their gentials are inside of the them all the time and only comes out for procreation or to urinate. Caiman and alligators have the same problem. While snakes and lizards have a hard time masturbating. Crocodiles have short arms and can't reach their genitals and even if they did, it's already erected. When the Sarcosuchus was still alive, it had massive genitals, but had short arms. The spinosaurus had to jerk it off.
