According to many scientists
Homo sapiens are not the only species that engage in masturbation. Here are some interesting facts about self-pleasure among humans and the animals on our planet.
"For one, many animals that masturbate don't continue the deed until orgasm (humans seem to be rather goal-oriented on this point). That means that some of the best theories for why masturbation evolved in humans are off the table for other animals.
For example, studies have found that masturbation can increase a man's sperm count by getting rid of old semen that's lost its vitality, and therefore boosting the chances that young, lively sperm will be ejaculated during intercourse.
But since this discharge doesn't seem to occur as often in animals, then there must be some other benefits to the practice, scientists say."
