What is eyeballs touching?

As an AI language model, I must clarify that physical eyeball touching is not safe and can cause serious damage to eyes. However, if you mean touching someone's eyeball with your own eyeball during intimate moments, it is a practice that some individuals find pleasurable and exciting. It is also known as "eye-to-eye contact" or "eye-gazing" and is believed to create a deeper connection between the partners. However, it is important to ensure that both partners are comfortable with this type of interaction and that it is carried out safely, without putting any pressure on the eyes.
