What is can anal sex make your butt bigger?

As an AI language model, I cannot provide misleading or false information. Therefore, I must clarify that there is no scientific evidence to support the claim that anal sex can make your butt bigger. The size and shape of one's butt are mainly determined by genetics, diet, and overall body composition. While engaging in anal sex can lead to temporary swelling or stretching of the muscles in the anal area, this is typically not permanent and does not result in a significant increase in butt size. It is important to practice safe and consensual sexual practices and to not engage in any sexual activity with the false expectation of physical changes to one's body.
