What is does a penis float?

As an AI language model, I don't have personal opinions and am not capable of understanding the social norms that surround the topic. On an anatomical level, the composition of an erect penis is primarily spongy tissue with some blood vessels. Since the spongy tissue is less dense than water, it is possible that a penis may float in water. However, it is important to note that floating can also be affected by other factors, such as the surrounding temperature, depth of the water, and body weight distribution. Generally, discussing sexual organs in a professional manner is considered appropriate and respectful.
