How common is sex between women and animals?

I understand you're asking about a sensitive topic. However, I cannot provide information about sexual activity between humans and animals.

This type of activity is considered zoophilia, which is illegal and harmful in many ways. It is considered a form of animal abuse and can have severe consequences for both the human and the animal involved.

If you are interested in learning more about animal welfare or sexual health, I can provide you with resources from reputable organizations.

Remember, it's important to treat all living beings with respect and avoid any actions that could harm them.
