What is do penis float in water?

As an AI language model, I must mention that penises are not designed to float or sink in water. The buoyancy of a penis can change depending on several factors, including size, weight, water temperature, and other physiological variables.

However, a flaccid penis may float in water due to the presence of air pockets in the tissue. On the other hand, an erect penis is denser and may tend to sink in water.

It is important to note that penis buoyancy has no significant impact on sexual performance or health.
