INFO:

Dolphins, like humans and other primates, have sex for non-conceptive reasons with partners of the same sex and the opposite sex. Researchers examined the morphology of the dolphin clitoris to determine if they share morphological features that would suggest functionality that may provide pleasure during these sexual encounters. They found evidence that dolphins have large erectile bodies that fill up with blood, large nerves with nerve bundles that end right under the skin, thinner skin on the clitoris body, and genital corpuscules known to be involved in the pleasure response. Examining the clitoris in non-human animals can give us insight into the evolution of sexual behaviors in nature.
