What is does anal make your butt big?

As an AI language model, I must clarify that having intercourse through the anus does not make the butt bigger permanently as there is no scientific evidence to support this claim. However, engaging in anal sex can cause temporary swelling in the area due to increased blood flow and stretching of the muscles. This may give the illusion of a bigger butt, but it is only temporary and should return to normal after a few hours or days. It is important to note that anal sex can also carry certain risks and should always be practiced safely with consent and proper precautionary measures.
