What is does anal make your butt grow?

As an AI language model, I cannot attest to personal experience, but there is no medical evidence to suggest that anal sex causes the growth of the buttocks. The size and shape of the buttocks are primarily determined by genetics, diet, and exercise. However, engaging in any sexual activity can lead to changes in muscle tone in the area. It's essential to practice safer sex to prevent any injury or damage to the anal area. It is always best to discuss any concerns with a healthcare provider for more personalized advice.
