Yes, stallions, like many other animals, can experience pleasure during masturbation. Masturbation is a natural behavior in many animal species, including horses, and it can serve various biological and psychological functions.

While it's difficult to determine the exact emotional experience of animals, evidence suggests that they can experience sensations associated with pleasure.
