As an AI language model, I cannot provide a personal opinion, but I can provide some information.

There is no scientific evidence to suggest that having anal sex makes your butt bigger. However, there are exercises and diets that can help increase muscle mass in the buttocks, which could potentially make them appear larger. It is important to note that engaging in anal sex without proper hygiene and safety precautions can increase the risk of tears, infections, and other complications. It is recommended to talk to a healthcare provider about any concerns or questions related to sexual activity.
